When the ABI is 64-bit on Linux ELF, add /lib64 and /usr/lib64 to the
system library path so that an RPATH is not added when using libraries
from these directories.
I got the impression that Linux systems which are completely 64-bit
(i.e. don't support executing 32-bit binaries) don't use /lib64 and
Well, actually, the search paths to system libs is hard coded into gcc.
It may vary between architectures, vendors and OSes.
