First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).
Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.
Kernel must be compiled with "options COMPAT_LINUX" for this to work.
