[SPARC64]: Stop putting -finline-limit=XXX into CFLAGS 



It was a stupid workaround for the "static inline" vs.
"extern inline" issues of long ago, and it is what causes
schedule() to be inlined like crazy into kernel/sched.c
when -Os is specified.

MIPS and S390 should probably do the same.

Now CC_OPTIMIZE_FOR_SIZE can be safely used on sparc64
once more.
