Log message:
Restrict gcc gsed usage to NetBSD
(NetBSD/mips64 progress further with gsed)

Adding gsed as a tool creates circular dependencies if pkgsrc gcc is used
as the bootstrap compiler.

Pointed out by jperkin, sorry.

Log message:
Use gsed when building GCC.

This is a somewhat blind commit. I've long had issues on various platforms
with libgcc getting misconfigured (on netbsd/mips,arm,powerpc), for example
build failures see:
http://mail-index.netbsd.org/port-mips/2017/06/21/msg000832.html

testing GCC 7.1 with netbsd/mips64el I got a lot further using it, but
still didn't complete the build. It took hours to reach this failure,
so I'd rather blindly commit the same change in the hopes it might help
other architectures.

Log message:
Take maintainership of all (recent-ish) GCC packages

I have gone into the depths of GCC and came back alive, so feel free
to ask me about it.

Log message:
gcc48: always link libgcc on netbsd (GCC r248037,
applied to GCC 8 and above - thanks Krister Walfridsson)

libstdc++: if it thinks vswprintf is broken, don't block the
entire definition of to_string, just that of to_wstring. backport
of GCC r223830 already applied to GCC 4.9. this applies to netbsd-6-0.

Doesn't fix any build I wanted to fix, but it does get the build
of LLVM4.x further on netbsd-6-0. maybe there's an odd package that
could benefit from it.

bump PKGREVISION.

Log message:
gcc48: fix build with newer (e.g. pkgsrc version) gtexinfo.
should help failing CentOS builds.

Log message:
provide a consistent description across gcc packages.

don't mention netbsd things, development snapshots, etc.

Log message:
Do not build with the gcc-java enabled by default.
Add a comment to note the removal of option.

Log message:
gcc48: fix build error on netbsd/arm

configs for gcc on netbsd don't build -march=native support, but this
stray prototype was left, causing build errors:

gcc.o:(.rodata+0x58c4): undefined reference to
`host_detect_local_cpu(int, char const**)'

Log message:
gcc48: restore distinfo for file grabbed only when building gcc-java
pointed out by jperkin, thanks

fix netbsd gcc-java option build
netbsd has gethostbyname_r in libc, but not in any headers.
configure test succeeds, but compilation fails.
workaround with passing ac_cv_func_gethostbyname_r=no to autoconf
thanks joerg for the suggestion.
