Hmm.... You are right, I switched compilers because building alpha in 3.16 failed
with a kallsyms error when using gcc 4.8.3 (or 4.6.3). Oh well.

I switched back to using gcc 4.8.3 for 3.2 and 3.4.

Now I get a crash with the nosmp qemu test, and

{standard input}: Assembler messages:
{standard input}:343: Error: Unrecognized opcode `ll$4, 0($3)'
{standard input}:346: Error: Unrecognized opcode `sc$4, 0($3)'
scripts/Makefile.build:305: recipe for target 'arch/mips/mm/ioremap.o' failed
make[2]: *** [arch/mips/mm/ioremap.o] Error 1
make[2]: *** Waiting for unfinished jobs....

when building mips:malta_defconfig. Bisect points to
'MIPS: Adjust set_pte() SMP fix to handle R10000_LLSC_WAR'.

for the build error.
