I dug around in the archives a bit and failed to find much of any
discussion since the original addition of LDFLAGS_SL in 2004.  I did
find a couple of things showing the reasons why AIX has LDFLAGS_SL
there, eg,
http://archives.postgresql.org/pgsql-bugs/2005-12/msg00061.php
but that just confirms my feeling that Makefile.aix has this right
and the other platforms are a brick shy of a load.

Do you have any specific objection to the proposal I made, ie
LDFLAGS = switches for linking both executables and shlibsLDFLAGS_EX = extra switches for linking executables
onlyLDFLAGS_SL= extra switches for linking shlibs only
 

which'd imply adding LDFLAGS and LDFLAGS_SL to all the .o-to-.so rules?
