fix find_library when cross-compiling 32-bit on 64-bit systems

When find_library is used to find dependencies, meson checks all paths for
libraries with all prefixes that could match. This means that when we are
compiling with -m32 on a 64-bit system, meson will find 64-bit libraries and
assumes that they will work. Naturally that is not the case.

The obvious fix is to do a test link against those libraries, but the extra
wrinkle here is that we need to do a "whole link" so as to test the static
libs. A check with gcc+ld on linux shows that unless there are unresolved
symbols from the main.c file, the static library is never checked so we avoid
the error from an incompatible library.
