stuff: bz2 support, compress support, many non-required options.
now x_gzip supports "gzip -l" so sysinst should work for these platforms.
gzip will grow slightly - 400 or so bytes on x86 - but this is a small
price to pay for working -l support...
The same change has already been applied on the 1.5 branch. The problems
(i.e. ifconfig not showing IP addresses) have been verified to still exist
with the new toolchain.
