Log message:
gcc49: backport upstream security fix

Incorrect codegen from rdseed intrinsic use (CVE-2017-11671)

We should not expand call arguments in between flags reg setting and
flags reg using instructions, as it may expand with flags reg
clobbering insn (ADD in this case).

Attached patch moves expansion out of the link. Also, change
zero-extension to non-flags reg clobbering sequence in case we perform
zero-extension with and.

Log message:
gcc{48,49}: netbsd also provides libssp in libc, adjust LINK_SSP_SPEC accordingly.
already done for newer versions of gcc.

Now on netbsd all gcc packages can successfully build with -fstack-protector.

bump pkgrevision (sorry)

Log message:
gcc{48,49,5,7}: on netbsd only, bump libstdc++ major to 7.
bump pkgrevision.

while here, synchronize libssp comment to a clearer one.

bump gcc*-lib revision to be one higher.

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:
gcc49: on netbsd, always link against libgcc. from Krister Walfridsson

bump PKGREVISION

Log message:
gcc49: don't use precompiled headers for libstdc++

this is a build time optimization that causes hangs on some machines
(netbsd-7/i386, but not netbsd-7/amd64). disable it globally instead
of guessing which are broken.

gcc{5,6} are already disabling it.
