Here is a first version of the patch. Granted, detecting multiarch

the result is quite ugly for now.
What about adding a small C file that we compile at configure
time and can run with various arguments. Such as:
int main(int argc, char **argv)
{
switch(argc == 1 ? argv[1][0] : 0) {
case 'v': <print __GNUC__>
case 'm': <print __GNUC_MINOR__>
case 'a': <print [MULTI_]ARCH_TRIPLE>
case 'e': <print endian-ness>
...
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.
and use as:
gcc_major=`our-config-tool v`
etc...
That way configure would look better without that inline C code.
Ok, I can do that.
