Could you post the output of adding "-v" to that gcc command line.  ie
it would help to see the exact command line that GCC is using to
invoke collect2.

It looks like this "map.below4G" file is supposed to be a linker
script, but that either the linker thinks that it is an object file or
else it thinks that it is a script, but not in a scripting language
that it understands.

The former theory would seem to imply that a -T switch is missing from
the linker command line, the latter theory that this map.below4G file
is in a syntax specific to Sun's linker and that it should not be
present on the command line to the GNU linker at all.  Or possibly
that you should be using Sun's linker and not the GNU linker.
