I'm running makepp from within a GNU Makefile (since my entire
build flow is not [yet] converted to makepp at this time).
The GNU Makefile was run with some command-line args set, like
So GNU Make sets $MAKEFLAGS which makepp sees.
Unfortunately line 1077 of makepp (1.40beta1) adds a '-' character to
the front of MAKEFLAGS, if one doesn't already exist. This causes
CONFIG=foo to become -CONFIG=foo, which tells makepp to try to
find a directory named ONFIG=foo:
makepp: error: No rule to make
makepp: error: status (-1), stopping now
make: *** [all] Error 1
