Why not but strike multiarch from that as I don't see how we could 
detect it by compiling a C program. The place where headers, libraries 
and crt*.o files are stored is transparent to programs, only compilers 
need to care about. There isn't any macro defined by the compiler. 
That's why it's detected by checking whether crti.o is in /usr/lib[64] 
or not.

Ok, I can do that.
