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.
Add support for libstd++ in full locale mode, and remove the need for
config hacks when using uClibc stub locale support.
TODO --
gdb intl support is still broken.
uClibc should auto-download the pregenerated locale data
