I concur -- Slackware and virtually every other distro ship with native
compilers only.

Not likely -- cross compilers for other architectures are typicially given
the name <os>-<cpu>-<program> and usually reside in /usr/<os>-<cpu>/bin. Eg,
for a strongarm gcc built for Linux, the name would be linux-strongarm-gcc.

The only way I know of being able to compile for both my native architecture
and a foriegn one is by installing two different copies of the compiler and
toolchain -- one configured for native builds, and another for foriegn. It
is possible, however, to tell the compiler to build for a different
architecture, as long as that arch is in the same family. Hence why we can
specify the -march=i486 when GCC is compiled to build for the Intel
architecture.
