Which FPC branch do you use, trunk or fixes? If it is trunk, it should be
able to use not only the internal assembler but also internal linker and
thus these binutils are not used at all (unless also using -Xe). If it is
fixes, then I wonder what happens there because the linker included in the
package above completely refuses object files created by FPC 2.6.2
(admittedly, I haven't tested a fixes snapshot, but I wouldn't expect
major changes in this area merged to fixes) - the linker complains about
unsupported section type and doesn't find the required symbols.
