Add a --multiarch-triplet switch to configure

Add a --multiarch-triplet switch to configure. The switch will allow
files to be search for each default path in path/<triplet> and then
path.
Default paths handled that way:
- CONFIG_TCC_SYSINCLUDE_PATHS
- CONFIG_TCC_LIBPATH
- path to crt*.o
- path to libgcc_s.so.1

Path missing: elf interpreter path (will be handled in another commit)
