When your kernel has the FPU emulation code included  you  should  be
able  to run the tools from a standard LinuxPPC distribution; this is
probably not optimal but the  easiest  way  to  get  startet  and  to
provide the full working environment for NFS based systems.

This way you only need to recompile/optimize those tools  you  really
put into your embedded system.

Any of the GNU archives, of course. See ftp://prep.ai.mit.edu/pub/gnu
for a starting point and a list of mirror sites.

RPM's are already a higl-level  issue;  usually  you  will  find  the
sources in (compressed) tarballs.

RTFM for RPM! Use "rpm -qa" to get a listing of all installed  RPM's,
and "rpm -ql ql <rpm_name>" to get a list of files that come with RPM
<rpm_name>.

Use
	rpm -qf `which ls`
to find out that "ls" belongs to the fileutils RPM (and thus compiles
from the sources in the fileutils tarball from your GNU mirror site).
