Fixes the following problem when testing a cross-compiler:

============================================
Testing g++.dg/compat/abi/bitfield1,
...
Invoking the compiler as /crosstool-0.12/build/powerpc-750-linux-gnu/gcc-3.3-glibc-2.2.5/build-gcc/gcc/testsuite/../g++  ...
/crosstool-0.12/build/powerpc-750-linux-gnu/gcc-3.3-glibc-2.2.5/gcc-3.3/gcc/testsuite/g++.dg/compat/abi/bitfield1_main.C
pid is 16028 -16028
compiler exited with status 1
output is:
sh: error while loading shared libraries: /opt/cegl-2.0/powerpc-750-linux-gnu/gcc-3.3-glibc-2.2.5/powerpc-750-linux-gnu/./lib/libdl.so.2: ELF file data encoding not little-endian
