autodetection of system compiler libpath is completely bogus

[Marc Espie]

Trying to detect statically where the compiler/linker gets its system
libraries is completely bogus.

It does not work on any system with multi-libbing enabled.

For instance, the actual branch of gcc used within OpenBSD does need
a separate libgcc for pic code for various reasons, and 
every version of libtool I've seen insists in looking for these in
/usr/lib/gcc-lib/i386-unknown-openbsd3.0
instead of
/usr/lib/gcc-lib/i386-unknown-openbsd3.0/fpic
as it should, for shared libraries.
