Subject: [PATCH 2/2] build.mak.in: Filter out 3rd party libraries from
 PJ_INSTALL_LDFLAGS.

This is done so users of the installed pjproject libraries do not get
directives (provided via pkg-config file of pjproject) to link against
pjproject's own library dependencies.

* build.mak.in (THIRD_PARTY_LIBRARIES): New variable.
(PJ_INSTALL_LDFLAGS): Filter out THIRD_PARTY_LIBRARIES.
