Log message:
Convert to buildlink3.

Log message:
In the new compiler selection framework, GCC_REQD is appended to, not
overridden.

Log message:
Use GCC_REQD instead of USE_PKGSRC_GCC when overriding the compiler
for arm, so that we don't need to install the gcc package(s) on
machines that already have a working compiler in their /usr/bin.

Log message:
Move WRKSRC definition away from the first paragraph in a Makefile.

Log message:
get rid of USE_GCC2/3 in pkg Makefiles, and set GCC_REQD or
USE_PKGSRC_GCC as appropriate, as this is handled by compiler.mk now.

Log message:
kill all references to gcc.buildlink2.mk and compiler.mk, and define
USE_GCC2 or USE_GCC3 where appropriate.

the functionality of the old gcc.buildlink2.mk has been rolled into
compiler.mk now, which is automatically used.

more changes to come later...

Log message:
Update for the fact that 'arm' ports have been called NetBSD-*-arm for a while
now and not NetBSD-*-arm32. Changes include one or more of:
    - Change MACHINE_ARCH == arm32 to also match arm
    - Where ONLY_FOR_PLATFORM includes NetBSD-*-arm32, add NetBSD-*-arm
    - Where BROKEN or worked around for arm gcc bugs, set USE_GCC3
The last may shake out a few more broken packages the next bulk build.

Log message:
Use mk/gcc.buildlink2.mk rather than gcc/buildlink2.mk so lang/gcc3
is accepted. Suggested by Grant.

Log message:
Place WRKSRC where it belongs, to make pkglint happy; ok'ed by wiz.

Log message:
Use new IMAKE_MAN_DIR variables in PLISTs to make these packages more
portable.  Bump PKGREVISION accordingly.
