i686-linux to sparc-sun-solaris2.5.1 cross compile problems

[Theofilos Intzoglou <teo at programmer dot net>]

Everything goes well until it tries to build libiberty. It runs configure
and then I get this error that it compiler cannot create executables. Here
is the whole output:

It has given me another error previously that it couldn't find some
include files, so I edited manually the Makefile and inserted in the
include variable the path /usr/include (Note that this include files are
from linux. Does it matter?) Please help me. It is the first time I try to
build a cross compiler. I have build gcc for my system (linux) correctly
before... Thanks in advance!
