localmodconfig: Add debug environment variable LOCALMODCONFIG_DEBUG
If the environment variable LOCALMODCONFIG_DEBUG is set, then debug output
will appear in the make localmodconfig. This will simplify debugging what
people get with their output, as I can just tell people to do:
LOCALMODCONFIG_DEBUG=1 make localmodconfig 2>out.txt
and have them send me the out.txt. I'll be able to see why things are not
working as they think it should be.
