Short answer: Install slackware on a separate partition and chroot
yourself there.

Long answer: Read the glibc and gcc documentation for how that might be
done.  It probably involves specifying --dynamic-linker=/lib/ld.so and a
few other goodies.  You'll need the old libc5 headers in place when you
compile libc5 programs.  You might want to read up on some of the small
linux distributions which do this already, ie: tomsrtbt, etc.
