I've committed the attached (mainline and 6.2 branch).  This also goes 
through the MAINTAINERS file marking all affected architectures as 
"broken" (so that gdb_mbuild.sh skips them).

	and h8300 as broken.

	specific comments.

+GDB's internal frame infrastructure has been completely rewritten.

+mn10300-*-*
+ns32k-*-*
+sh64-*-*
+v850-*-*

+Unless there is activity to revive these configurations, they will be
+made OBSOLETE in GDB 6.3, and REMOVED from GDB 6.4.
