Log message:
libtool*: update to 2.4.7

* Noteworthy changes in release 2.4.7 (2022-03-16) [stable]

** New features:

  - Libtool script now supports (configure-time and runtime) ARFLAGS
    variable, which obsoletes AR_FLAGS.  This is due to naming conventions
    among other *FLAGS and to be consistent with Automake's ARFLAGS.

  - Gnulib testsuite is enabled and run during 'make check'.

  - Support the Windows version of the Intel C Compiler (icl) in
    libtool script.

  - Pass '-fsanitize=*' flags for GCC and LLVM, and '-specs=*' for GCC
    to linker.

  - Pass '-Xassembler=*' and '-Wa,*' flag to compilers and linkers.

  - The variable 'FILECMD' with default value of '/usr/bin/file' was used to
    replace existing hard coded references to '/usr/bin/file'.

  - Add MidnightBSD support.

** Important incompatible changes:

  - Libtool changed ARFLAGS/AR_FLAGS default from 'cru' to 'cr'.

  - Do not pass '-pthread' to Solaris linker.

  - 'libtool' and 'libtoolize' scripts now use '#! /usr/bin/env sh' shebang.
    Previously '#! /bin/sh' was used, which presents challenges for
    containerized environments.

** Bug fixes:

  - Fix significant slowdown of libtoolize for certain projects (regression
    introduced in 2.4.3 release) caused by infinite m4 macro recursion.

  - Mitigate the slowdown of libtool script (introduced in v2.4.3) caused by
    increased number of calls to '$SED $sed_quote_subst' (bug#20006).

  - Properly parse and export TLS symbols on AIX.

  - Various bug fixes surrounding use of 'sed'.

  - Darwin systems set proper "allow undefined" flag on OSX 11, and
    PowerPC 10.5.

  - Removed some deprecated tests related to 'Makefile.inc' files.

Log message:
Remove SVR4_PKGNAME, per discussion on tech-pkg.

Log message:
Resolves:
"INFO_FILES should be set to YES or yes."
"Packages that install info files should set INFO_FILES."
Makefile and PLIST warning, respectively.

Log message:
Update to libtool-2.2.6b. This switches libtool to the new main branch.
Changes are many, important for pkgsrc:
- much higher speed (up to 30% faster for the overall build of libX11)
- less magic for detection of the tag

The pkgsrc integration of f2c has been changed to be more sane.
libtool itself now depends on the f2c frontend to use proper
auto-configuration and only fakes up the library. This part is
encapsulated in mk/compiler/f2c.mk.

Log message:
Use BUILD_DIRS instead of manual rules.

Log message:
* Move info file entries into the PLIST.
* Honor PKGINFODIR and EMACS_INFOPREFIX.

Log message:
* Teach the tools framework how to supply the pkgsrc version of
  makeinfo if no native makeinfo executable exists.  Honor TEXINFO_REQD
  when determining whether the native makeinfo can be used.

* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.

* Get rid of all the "split" argument deduction for makeinfo since
  the PLIST module already handles varying numbers of split info files
  correctly.

NOTE: Platforms that have "makeinfo" in the base system should check
      that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
      correct.

Log message:
Update libtool* packages to account for libltdl split, and simplify by
moving some common things into Makefile.common.
