[LLVMbugs] Can't build LLVM after last changes in SystemUtils.cpp

[Vladimir Merzliakov]

As temporary fix use:
1) add #include <signal.h>
In Linux and FreeBSD kill declaration in this file

2) replace SA_NOMASK by SA_NODEFER
FreeBSD dosn't have SA_NOMASK define but have (and Linux also) SA_NODEFER

I don't undestand configure magic so can't prepare patch, sorry :(
