Yes, the _paths_ would have to be the same. But when cross-compiling
the patched macro won't _use_ e.g. link to the lib found there. It
will only check for the presence and record the path.
As said the main benefit would be to have the same simple optin
(--with=bdb) for both compilation cases without the necessity to
fiddle with anything else.

Another possible albeit completly different and simple solution would
be to check if BDB_CFLAGS, BDB_LIBS, BDB_BIN and BDB_PATH are already
set and if theya re completly skip all checks.
