New Revision: 161

Modified:
   buildrom-devel/Makefile
Log:

This is a performance patch. Switch the definition of BASE_DIR from a
recursively expanded variable to a simply expanded variable (cf.
http://www.gnu.org/software/make/manual/make.html#Flavors), so that `pwd` does
not get executed dozens of times for each run of make.

This is a trivial patch.
