Change to RULES.Db between 3.14.8.2 and 3.14.11 -I../O.Common no longer in include paths

["Allison, Stephanie" <saa@slac.stanford.edu>]

Hello,

The following line was removed from RULES.Db sometime between epics base 3.14.8.2 and 3.14.11:

DBFLAGS += -I$(COMMON_DIR)

where
COMMON_DIR = ../O.Common

This means that a database built from a substitutions file that depends on a database already built in O.Common will fail.

For instance, if the Makefile looks like this:

...
DB += aabb.db
DB += ccdd.db
...

and the directory contains:
aabb.substitutions
ccdd.substitutions
and
ccdd.substitutions includes aabb.db,  the build will now fail.

Can the "DBFLAGS += -I$(COMMON_DIR)" be added back to RULES.Db?  If no, is there another solution to this problem?  Other than creating subdirectories under Db and building in the proper order.

Thank you,
Stephanie Allison
