Can't build HEAD on OS X

[Johan Tibell]

I've unblocked myself with this change:

diff --git a/rts/ghc.mk b/rts/ghc.mk
index 3929adb..b96df3d 100644
--- a/rts/ghc.mk
+++ b/rts/ghc.mk
@@ -427,7 +427,7 @@ rts/win32/ThrIOManager_CC_OPTS += -w

 # Without this, thread_obj will not be inlined (at least on x86 with GCC
4.1.0)
 ifneq "$(CC_CLANG_BACKEND)" "1"
-rts/sm/Compact_CC_OPTS += -finline-limit=2500
+# rts/sm/Compact_CC_OPTS += -finline-limit=2500
 endif

 # -O3 helps unroll some loops (especially in copy() with a constant
argument).

That #ifneq check doesn't work because 1) gcc is not clang (I used
/usr/local/bin/gcc-4.9) but 2) the cpp that actually gets called during the
build is 'gcc -E', which is clang.
