The big problem with this approach, and the reason why it has been 
rejected before (both for ld and gcc) is that it makes reproducing a bug 
much harder.  Unless you remember that the environment variable has been 
set, (assuming that you know about it, quite often this kind of thing is 
done for you in a system wide initialisation script), then you might not 
report it when submitting a bug report or take it into consideration 
when investigating a bug.

Using wrapper scripts also has the same problem.  By far the best way is 
to spend the effort to create a good build environment where extra 
linker command line switches can be set on the build command line.

Cheers
