Bug #41455 ext/dba/config.m4 pollutes global $LIBS and $LDFLAGS

--enable-dba=shared --with-db4=... causes the main php binary be linked against libdb-4.x. It's because the test in ext/dba/config.m4 fails to reset $LIBS and $LDFLAGS. I'll attach a patch.

Reproduce code:
compile with the above options

Expected result:
the cli binary / apache module not linked against libdb-4.x

Actual result:
ldd -u -r /usr/bin/php5
 Unused direct dependencies:

Where can I attach a file? :)

Hopefully the lines won't wrap:

breaking out of the for loop right after the link test leaves $LIBS and
$LDFLAGS with their temporary values
