Building llvm error on Mageia2

Attempting to build llvm on Mageia2 from the 3.3 source I get:

The include path does not contain the path to the C standard library
include files where cxxabi.h resides. On Mageia2 this is at
/usr/lib/gcc/x86_64-mageia-linux-gnu/4.6.3/include/. Why ?

This was solved by forcing the llvm/configure to use gcc rather than clang as its compiler.
