Revision: 12798

Log Message:
-----------
Propagate CXXFLAGS and drop -fvisibility=hidden from both the CFLAGS
and CXXFLAGS environment variables for the automatically configured
build packages.  This change is made because some of the software
packages whose builds are automatically configured by the procedure
described in README.developers) do not have gcc visibility support so
it is easiest for now (until most do have visibility support) to drop
that possibility for all of these packages.
