This wouldn't work for Debian and Debian-derived systems that support full
multiarch, not just the biarch system that Red Hat initially implemented.

The variation that probably would work for those systems would be to allow
the expansion of $ISA to be defined at compile time, so that on Debian
amd64 (for example) it would be defined as "/x86_64-linux-gnu/".  But that
probably wouldn't be enough for Solaris, where you want to search multiple
paths.
