Tom Lane dd4e836748 Prevent accidental linking of system-supplied copies of libpq.so etc. ... Back-patch commit dddfc4cb2, which broke LDFLAGS and related Makefile variables into two parts, one for within-build-tree library references and one for external libraries, to ensure that the order of -L flags has all of the former before all of the latter. This turns out to fix a problem recently noted on buildfarm member peripatus, that we attempted to incorporate code from libpgport.a into a shared library. That will fail on platforms that are sticky about putting non-PIC code into shared libraries. (It's quite surprising we hadn't seen such failures before, since the code in question has been like that for a long time.) I think that peripatus' problem could have been fixed with just a subset of this patch; but since the previous issue of accidentally linking to the wrong copy of a Postgres shlib seems likely to bite people in the field, let's just back-patch the whole change. Now that commit dddfc4cb2 has survived some beta testing, I'm less afraid to back-patch it than I was at the time. This also fixes undesired inclusion of "-DFRONTEND" in pg_config's CPPFLAGS output (in 9.6 and up) and undesired inclusion of "-L../../src/common" in its LDFLAGS output (in all supported branches). Back-patch to v10 and older branches; this is already in v11. Discussion: https://postgr.es/m/20180704234304.bq2dxispefl65odz@ler-imac.local		2018-07-09 17:23:32 -04:00
