This is now complete. I have now finished in the hal/ directory, so I
have no objection to people checking in more changes in there.
There are an awful lot of platforms which fail to build.
ARM
AEB, all SA1110: cxxsupp fails to link because of .gcc_except_table.

SH
All platforms fail to build cxxsupp
i386, cortexm, and m68k all build fine.
I have not tried anything with the calmrisc16, calmrisc32, coldfire,
fr30, frv, h8300, mn10300, openrisc, sparc, sparclite or v85x targets.
The synthetic target builds fine, but there is a run-time problem with
cxxsupp. It appears that libgcc now assumes that glibc has done some
initialization, setting up the %gs register to point at per-thread
data. This came up previously in the context of the -fstack-protector
flag, see the mailing list archives, but at the time we decided we
could live with the problem. It looks like there are now more
dependencies on getting this sorted - which I suspect will prove
challenging.
