Extended Description

llvm-gcc4 code lacks static ctors & dtors at least on Linux (mingw has its own
technique to handle this and everything is ok there). This breaks many apps,
e.q. Qt.

The problem will solved (I hope), when crtstuff.c will be properly compiled with
llvm-gcc4.

Well, It seems, that LLVM is mature enough to compile crtstuff.c properly with
just few minor glitches. Please find attached 2 patches: one for LLVM itself,
one for llvm-gcc4 which enables static ctors & dtors at least on linux platform.

Test .cpp file is also attached.
