I am trying to build a crosscompiler (gcc-4.1.2, binutils-2.15, freebsd-8.0)
with target as x86_64-freebsd and host as i686-linux. Everything builds successfully but compiler-assist libraries (libgcc_s, libstdc++, etc.) are
Linux library, not a FreeBSD one.
$ file gcc-4.1.2/x86_64-freebsd8.0/lib/libstdc++.so.6.8
gcc-4.1.2/x86_64-freebsd8.0/lib/libstdc++.so.6.8: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

If I build with binutils-2.17.50.15 everything is fine.
$ file gcc-4.1.2/x86_64-freebsd8.0/lib/libstdc++.so.6.8
gcc-4.1.2/x86_64-freebsd8.0/lib/libstdc++.so.6.8: ELF 64-bit LSB shared object, x86-64, version 1 (FreeBSD), dynamically linked, stripped

Same is the case for freebsd6.0,6.3....
