Quotes are important to make sure the argument to test -n really
is the empty string, but that requires stringifying PROGRAM_DIRS.

SUBDIRS just takes PROGRAM_DIRS value. If PROGRAM_DIRS gets set
to the empty string (as can happen when building only OSMesa), a
'for' loop will lack anything to iterate over, causing a parse
error.
This fixes the issue by making sure SUBDIRS is the null string
when PROGRAM_DIRS is, and wrapping the for loops in if's, causing
them only to execute if there are directories to iterate over.
Mostly some pedantic changes such that `make clean' always ignores
errors. Also changed the top clean target to do the `touch
configs/current' dance instead of realclean.
In general, use this:
@for dir in $(SUBDIRS) ; do \
if [ -d $$dir ] ; then \
(cd $$dir && $(MAKE)) || exit 1; \
fi \
done
Basically, silently skip missing subdirs but generate an error and stop if
there's a compilation or install problem.
This was done inconsistantly before. In once case, a missing subdir was
causing us to go into an infinte loop!
variable (defaults to "make") and use that. Use the MKDEP and MKDEP_OPTIONS
more. Our shell isn't bash, so change the instances of ">& /dev/null" to a more
compatible "> /dev/null 2>&1".
and execute fragment programs. Very limited and experimental, but works
well enough to run arbfplight.c.

Compile with 'make linux-tcc', being sure to make clean first.
