Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Changes 1.51.0:
New Libraries
* Context: Context switching library, from Oliver Kowalke.
Updated Libraries
* Algorithm:
- Fixed is_sorted_until ; now matches the c++11 standard behavior on ranges with
  duplicate values.
- Added range support for the rest of the search algorithms.
- unhex now uses Boost.Exception to signal bad input.
* Asio:
- Fixed an incompatibility between ip::tcp::iostream and C++11.
- Decorated GCC attribute names with underscores to prevent interaction with
  user-defined macros.
- Added missing #include <cctype>, needed for some versions of MinGW.
- Changed to use gcc's atomic builtins on ARM CPUs, when available.
- Changed strand destruction to be a no-op, to allow strand objects to be
  destroyed after their associated io_service has been destroyed.
- Added support for some newer versions of glibc which provide the
  epoll_create1() function but always fail with ENOSYS.
- Changed the SSL implementation to throw an exception if SSL engine
  initialisation fails.
- Fixed another regression in buffered_write_stream.
- Implemented various minor performance improvements, primarily targeted at
  Linux x86 and x86-64 platforms.
* Config:
- Deprecated a whole bunch of macros that were c++11 specific, but not named to
  show that they were c++11 specific. Made new macros with better names, and
  paired the old macros with the new ones. Updated the documentation to list
  the deprecated macros.

New Libraries
* Algorithm: A collection of useful generic algorithms, from Marshall Clow.
  This includes several different searching algorithms, as well as most of the
  new algorithms from the C++11 standard library
* Functional/OverloadedFunction: Overload different functions into a single
  function object, from Lorenzo Caminiti.
* LocalFunction: Program functions locally, within other functions, directly
  within the scope where they are needed, from Lorenzo Caminiti.
* Utility/IdentityType: Wrap types within round parenthesis so they can always
  be passed as macro parameters, from Lorenzo Caminiti.

Let's assume for now that everything that worked with python-2.6 also
works with python-2.7.

Changes 1.46.0:
New Libraries
* Icl: Interval Container Library, interval sets and maps and aggregation of
  associated values, from Joachim Faulhaber.
Updated Libraries
* Array:
  - Added support for cbegin/cend
  - Fixed a problem with the Sun compiler
* Asio:
  - Fixed a problem on older Linux kernels (where epoll is used without timerfd
    support) that prevents timely delivery of deadline_timer handlers, after
    the program has been running for some time
* Bind:
  - make_adaptable now documented
* Concept Check:
  - fixed warnings with self-assignment
* Filesystem:
  - Version 3 of the library is now the default.
  - IBM vacpp: Workaround for compiler bug affecting iterator_facade
  - Verify, clarify, document that <boost/config/user.hpp> can be used to
    specify BOOST_FILESYSTEM_VERSIO
  - Replaced C-style assert with BOOST_ASSERT.
  - Undeprecated unique_path(). Instead, add a note mentioning the workaround
   for lack of thread safety and possible change to cwd. unique_path() is just
   too convenient to deprecate!
  - Cleared several GCC warnings.
  - Changed V2 code to use BOOST_THROW_EXCEPTION.
  - Windows: Fix status() to report non-symlink reparse point correctly.
  - Add symlink_option to recursive_directory_iterator, allowing control over
    recursion into directory symlinks. Note that the default is changed to not
    recurse into directory symlinks.
  - Reference documentation cleanup, including fixing missing and broken links,
    and adding missing functions.
  - Miscellaneous implementation code cleanup.
* Fusion:
  - vector copy constructor now copies sequence members in the same order on \ 
different platforms
* Graph:
  - Fixed Graphviz output to work on Visual C++ 7.1.
  - Replaced assert with BOOST_ASSERT.
  - Changed to Boost.Filesystem v3.

Log message:
Changes 1.45.0:
* Fixed a problem on kqueue-based platforms where a deadline_timer
  may never fire if the io_service is running in a background thread
* Fixed a const-correctness issue that prevented valid uses of
  has_service<> from compiling
* Fixed MinGW cross-compilation
* Removed dependency on deprecated Boost.System functions
* Ensured close()/closesocket() failures are correctly propagated
* Added a check for errors returned by
  InitializeCriticalSectionAndSpinCount
* Added support for hardware flow control on QNX
* Always use pselect() on HP-UX, if it is available.
* Ensured handler arguments are passed as lvalues
* Fixed Windows build when thread support is disabled
* Fixed a Windows-specific problem where deadline_timer objects with
  expiry times set more than 5 minutes in the future may never expire
* Fixed the resolver backend on BSD platforms so that an empty service
  name resolves to port number 0, as per the documentation
* Fixed read operations so that they do not accept buffer sequences of
  type const_buffers_1
* Redefined Protocol and id to avoid clashing with Objective-C++ keywords
* Fixed a vector reallocation performance issue that can occur when
  there are many active deadline_timer objects
* Fixed the kqueue backend so that it compiles on NetBSD
* Fixed the socket io_control() implementation on 64-bit Mac OS X and
  BSD platforms
* Fixed a Windows-specific problem where failures from accept() are
  incorrectly treated as successes
* Deprecated the separate compilation header <boost/asio/impl/src.cpp>
  in favour of <boost/asio/impl/src.hpp>
