++When deciding which libraries are available, the original Configure uses
++shaky heuristics to physically locate library files.
++This is a very very bad thing to do, *especially* when cross-compiling,
++as said heiristics are likely to locate the host libraries, not the target ones.
++
++The only real need for this test is to make sure it's safe to pass -llibrary
++to the compiler. So that's exactly what perl-cross does, pass -llibrary
++and see if it breaks things.
++
++Note this is a part of MakeMaker, and only applies to module Makefiles.
