Initial attempt at getting Linux QMAGIC shared lib support. I have

Browse Source 
successfully run linux netscape 2.0b3 with a QMAGIC ld.so and libc/libm
that I found on some linux machine that I _think_ is running slackware 3.0.

There are still problems..  ld.so claims the libraries are the wrong
format, but it still runs anyway.. :-/  The QMAGIC ld.so also screams
about needing ld.so.cache, and running a linux ldconfig is quite
educational.  You soon learn to run "chroot /compat/linux /bin/ldconfig"
where ldconfig is living in /compat/linux/bin. :-]

(Lets just say that it puts loads of symlinks in /usr/lib otherwise :-)
