mkimage-profiles/profile.mk
Michael Shigorin 75fd795210 ensure that distcfg.mk gets included once at most
This was done while debugging GLOBAL_CLEANUP_PACKAGES
getting doubled... as it got no hard initial value but
rather was always added to, it appeared that at least
stage2/Makefile would obtain a once-initialized value
from upstream and double it while including distcfg.mk
itself.

It's way less hassle to just proxy the value once.
