A proper solution is not to try tricks like the one above, but to let 
the user specify the directory he needs, if he needs special settings.

In most cases he won't have to, because on e.g. on redhat-based systems,
/usr/lib64 is in of GCC's default library search path.

Seriously, simply not caring about "LIB_SUFFIX"es is the best solution.
