Configure, Makefile.SH: Allow running generate_uudmap in the target
This is a bit of a step backwards, but we want to run this in
the target platform when cross-compiling to some unusual setups,
like ASCII -> EBCDIC.
What this branch introduces is a third "path" for generate_uudmap:
* If we are doing a native build, just build it as usual and run it.
* If we're cross-compiling, and either -Dhostgenerate was specified OR
if it was left empty, which is the default case, then create
a host generate_uudmap and run it locally
* Finally, if are cross-compiling and were built with -Uhostgenerate,
then build generate_uudmap for the target and run it there, bringing
back the resulting headers.
