gcc-3.1 on Solaris 2.6 gets ld:libgcc/./libgcc.map:1: parse error

[William Bader]

I am trying to build gcc-3.1 on a Sun IPX under Solaris 2.6 using
gcc-2.7.2.3 and binutils-2.9.1 from http://www.sunfreeware.com .

The build dies with a complaint from ld that it can not recognize
the file libgcc.map.

Does anyone have any advice?
I can send the build log and config log if you want.
