Sage consists of about 100 different packages. Languages used include C, 
C++, Fortran, LISP, Python and possibly others.

Some of those bits of code currently assume the linker is GNU, and so 
send GNU options with the -Wl flag directly to the linker. That breaks 
if its the Sun linker, as one needs to use different flags. Normally the 
issue arises when building shared libraries.
