avoid adding /usr/lib

its configure.ac add /usr/lib (along with /usr/lib64) to library search path, clang assume -m32 arch.

patch to avoid searching /usr (/lib*) since it's already system default

This bug is NOT about a missing dependency. It's specific to using lld (or any linker which errors out, rather than warning, on incompatible objects).

The issue is that they do e.g. `gcc ... -L/usr/lib a.o`, then the linker sees incompatible objects in /usr/lib (like libc.so) and aborts rather than warning and looking in the default search locations.

My bad, I completely mis-read this.  Was hoping to file a stabilization bug, but plainly it's not ready except in niche cases, and for people willing to suffer a few issues.

It may well not be a regression, though.
