The libruntime gets not build with the problem being that not even the
compilation from CommonProfiling.ll to CommonProfiling.bc does not work. 

I have reduced it to 
$> .../Debug/bin/llvm-as .../runtime/libprofile/Debug/CommonProfiling.ll -o
test.bc
$> .../Debug/bin/opt -std-compile-opts -o
.../runtime/libprofile/Debug/CommonProfiling.bc < test.bc

Segmentation fault

Interesstingly this is not happening when opt gets the file on the command
line, not from stdin.
