This is a useless test.  Quite naturally, GNU ld will try to accept 
(i.e. ignore) popular Solaris linker options when used under Solaris 
and the Solaris tools will gradually attempt to accept popular GNU ld 
options because GCC is popular.  That does not mean that these options 
actually work.

These industry trends tend to break any algorithm which attempts to 
intuit the tool via feature testing.
