Log message:
gcc5: remove wip package leftover. fix typo in patch.
from Kai-Uwe Eckhardt

on netbsd, always link against libgcc.

bump PKGREVISION.

Log message:
Fix building on macOS: disable multilib (it requires fat-binaries); now builds \ 
without Command Line Tools.

Log message:
provide a consistent description across gcc packages.

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

Log message:
lang/gcc5: add patch to avoid declaring a prototype of host_detect_local_cpu
on platforms which do not include driver-arm.o in gcc/config.host, and do
not have this function. such as netbsd/arm.

an alternative would be to add driver-arm.o for the netbsd/arm case too, but
it would be diverging from netbsd base gcc, and /proc/cpuinfo which is needed
for this function to do anything useful is empty at least on my machine.

(I still can't complete a build on ARM)

Log message:
lang/gcc{5,6}: avoid overwriting previous extra_objs in gcc/config.gcc

No change for i386/amd64, but arm needs additional extra_objs to build.
Mistake was in a netbsd-specific part of configure as well.

Thanks to Richard Earnshaw and ktkachov at GCC for finding the problem.

Log message:
Fix path to elfdump on SmartOS.

Log message:
gcc5: netbsd-only: unconditionally disable libssp, use a saner specfile.

because we unconditionally disable libssp, we don't need the workaround
for ssp.h not found, so we can remove that part of that makefile.

bump gcc5 PKGREVISION
bump gcc5-libs PKGREVISION further than gcc5.

Log message:
Bump PKGREVISION for perl-5.24.0 for everything mentioning perl.

Log message:
Restore PKGSRC_USE_SSP test to the version before the update to 5.4.0,
so it works again (at least for me; if it doesn't for you, please
let me know).

Log message:
Update gcc5 to 5.4.0 and gcc5-libs to 5.4.0nb1

Changelog:
* Many bugs are fixed
