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:
Use public SHLIB_TYPE instead of private _OPSYS_SHLIB_TYPE.

Log message:
gcc49-lib: bump PKGREVISION above gcc49

Log message:
Reset PKGREVISION after 4.9.4 update.

Log message:
gcc49 netbsd-only: disable libssp, use a more sane specfile.

bump gcc49 PKGREVISION
bump gcc49-libs so it is a higher PKGREVISION than gcc49

Log message:
Bump lang/gcc49-libs PKGREVISION to stay ahead of lang/gcc49.

Log message:
Remove mk/find-prefix.mk usage from the lang category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Log message:
Decrease PKGREVISION after gcc49 update.

Log message:
Disable CHECK_SHLIBS for the GCC library packages.  The libraries will
find their parent GCC package libraries first in RPATH at install time
but will correctly resolve to their own copies at runtime thanks to the
additional paths encoded at build time.  Fixes CHECK_WRKREF builds.
