Pull up following revision(s) (requested by tsutsui in ticket #715):
	sys/arch/mips/mips/trap.c: revision 1.212
	sys/arch/sbmips/conf/GENERIC: revision 1.60
	sys/arch/mips/conf/Makefile.mips: revision 1.46
Preserve local symbols on linking a kernel so that
we can get more useful trace on ddb(4).
Bump SYMTAB_SPACE so that it fits again.
Use the kernel symbol table to see the beginning of the current
subroutine to get more proper backtrace on ddb(4).
In the previous code it scans backwards from the current PC
for the end of the previous subroutine and checks "jr ra" or
"jr k0" instructions, but it often fails because gcc is
so aggressive nowadays as to reorder instruction blocks
to create efficient code path by branch predict etc. and
"jr ra" is not always located at the end of subroutines.
No objection on port-mips.
