Move our old a.out utils to /usr/libexec/aout.
Enable binutils and put the utils in /usr/libexec/elf
Enable objformat, a little helper program that calls the right
utils based on /etc/objformat and $OBJFORMAT.
This will enable the ELF generating tools.
Remember that this is only step one, the system is still compiled
and run in a.out format ONLY.
Problem left to solve: The BSD manpages wins over the GNU equivalents
as the are installed last. We need to distinguish between the manpages
somehow...
