Not very many overall changes. Main ones include
1. Support for powerpc, arm32 and vax
2. Makefile.gcc can now be included by anything which depends on gcc versions.
If the version installed isn't 2.95.3 it'll add itself as a BUILD_DEPENDS.
(XXX: any of the makefile's in pkgsrc should be checked and change to use
this)
3. Remove special PLIST.NetBSD-sparc as it's no longer needed
4. Change post-extract loop to pick up any arch files from FILESDIR without
having to hardcode all the archs
5. Remove arch restrictions as this should work on any arch supported by the
main source tree as of 03/28/02
6. Add PKGREVISION as this clearly isn't stock 2.95.3 (it doesn't change
gcc --version so version checks won't care).
