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

Are these libraries consistently available for 64-bit Linux?  If not,
 should they be explicitly tested for before depending on them?

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.

I'm talking about the dynamic linker search path, which is determined
by glibc.
The dynamic linker's search path is not of much importance when linking.
