Don't error on GCC inlining warning in rts
The warning for reference:
```
rts/RaiseAsync.c: In function ‘throwToMsg’:
rts/SMPClosureOps.h:65:0: error:
error: inlining failed in call to ‘lockClosure’: call is unlikely
and code size would grow
rts/RaiseAsync.c:305:0: error: error: called from here
rts/SMPClosureOps.h:65:0: error:
error: inlining failed in call to ‘lockClosure’: call is unlikely
and code size would grow
```
This warning triggers on `gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-16)`
and it doesn't trigger with new GCCs.
Test Plan: build ghc/rts
