[uClibc] Buildroot.

[tom at ceisystems.com]

Last time, I think.  Sorry for the noise.  Anyway, this patch fixes the
source file downloads when executing a "make source", and a few
cut-and-paste (tm) errors in the *.mk files.  Again, this is a patch
against the current CVS sources, and includes my previous patch.

If anybody needs anything else, let me know.  I might start working on
getting the target optimizations working better, as I had this done on a
previous buildroot system I had customized.

Good Luck, and Enjoy,
