Can you do the same thing on linux?

The only prerequisite is a GCC & glibc & other required libraries combination
which produces apps for Linux/XYZ instead of only for the Linux version/distro

I think the LSB group is working on a toolchain that would fill this need; see
http://www.linuxbase.org/build/
Also, I'm about to submit crosstool to Fedora Extras,
though I suspect they'll only ship a restricted set of
crosstool toolchains (maybe crosscompilers targeting
all FC4-supported architectures), since each crosstool toolchain
.rpm is fairly sizable, 20-30MB.
I expect that eventually, such toolchains will in fact
come standard with Linux distributions to some extent.
