Just for the records the -l switch didn't work. gcc-mips was searching a
number of directories around the "gcc-lib/mips-dec-ultrix42" string with no
success. So I had to create the directory and symlink a good number (>100)
of header files from various include directories in my SUSE distribution.
My patience was rewarded.
