Fixes endianess problems with old a.out tools. This makes building

some cross toolchains possible.

This also changes some utilities's behavior slightly:
- nm, strip, size now handle any a.out format they know about.
- ranlib complains if it detects mixed archives (several object
formats for different boxes).

In the presence of mixed objects, you still have file, ranlib or ld
to prevent you from getting too confused...
