properly recursed.
The .for loop was defining a ${__dir} variable that was being set at a
different evaluation time than the target itself, so every 'cd ${__dir}'
became the last value that was in ${__dir}. This resulted in 'make obj'
not properly being ran in the tree that would leave .depend files
scattered around when 'make all' was ran in rescue/.
To fix this, define a CRUNCH_SRCDIR_* for every prog if it does not
already have one and then use that variable in every relevant place.
This allows simplifying some logic as well.
