Sorry, there was no discussion. It appeared to me that nobody cared
about the debug sets because each time there was a change in the
tree I had to go and fix them.

You might not want to compile, but you might want to debug. I.e.
debug sets + gdb. Think about the case where someone runs something,
and it core-dumps.  If gdb and the debug sets are installed we can
get a useful stack trace.

This was a mess and it still is (various flavors of debug sets).
I am working on cleaning it up. The point being here, is that if
you built with MKDEBUG/MKDEBUGLIB you ended up installing everything
and that takes too much space. Because of this (debug sets taking too
much space and not being separable during install) MKDEBUG does not set
-g to the compile flags, making the use of the debug sets limited.

The incentive for me to do this BTW was to get a RPI image < 1GB with
MKDEBUG/MKDEBUGLIB set which is now possible.

Please let me know if you have any better ideas on splitting the
sets.  I am working on spliting debug to debug and xdebug now so
that it mirrors what we have for other sets, and it is clear that
they should be separable.
