Add uClibc-0.9.29:
- associated patch set
- update the munging function to accomodate the new config variables
libfloat version was missing from the previous commit... :-(
Better handle the case where the sample directory already exist but isn't under revision control, and in case the destination file doesn't exist in the sample directory.

 The files rh62*.patch are from the Red Hat 6.2 file

 binutils-2.13.90.0.2-2.src.rpm

 I am trusting here that Red Hat's patches are appropriate for all CPU

 types.  If I'm wrong, just remove the offending patch...
