description:
update a bit.  delete ports that have switched to GCC 4.8.  with this
we still need significant work on these ports:

        - mips*
        - powerpc
        - sh*
        - vax
        - m68k*

the x86 platforms are probably ready to switch, but i'm not in a good
position to test them.  these platforms are probably ready to switch,
as they're still mostly in bringup mode anyway:

        - powerpc64
        - coldfire
        - ia64

     sandpoint works fine in multi-user, found an annoyance by com(4) change.

+[2] weird failures.
 [3] relocations fail in libgcc
+[4] cc1 gets segv compiling libgcc.
 [5] mips*eb kernels seem to work as well as gcc 4.5 ones.
-[7] shark atf-report fails with: Unexpected token `tc-start'; expected end of test program
-[8] m68k/vax/sh3 gcc seem to randomly get -fstack-protector/-Wstack-protector
+[6] there are some uncommited hacks.
+[7] m68k/vax/sh3 gcc seem to randomly get -fstack-protector/-Wstack-protector
     wrong, for example m68k flags alarm() as unprotected in
     libc/gen/alarm.c:53, vax ifinit() in sbin/routed/if.c:680.
    --> hacked around
-[9] LOONGSON kernel has general problems
-[10] mips64el fails -- something in /sbin/init or /rescue/init jumps to zero.
-    in -current.  a hack for o32 works.
-[11] weird failures.
-[12] cc1 gets segv compiling libgcc.
-[13] some answers about C99 support in libstdc++-v3 are wrong.
