Subject: gitweb/Makefile: prepare to merge into top-level Makefile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since the "gitweb/Makefile" was split out from the top-level Makefile
in 62331ef1637 (gitweb: Makefile improvements, 2010-01-30) we've kept
the inter-dependencies between the two, and worse have dealt with a
lot of duplication as a result.

In preparation for merging the two again add a MAK_DIR_GITWEB variable
to various rules in it. This will allow us to set this variable to
"gitweb/" as we include it in the top-level Makefile, which will
minimize the size of the subsequent diff.
