"optimization" being a general term here for whatever tweaks the user
sees fit. with CFLAGS these are definitely optimizations, with LDFLAGS i
don't know.

the thing is, some of them (e.g. CDBS) do set LDFLAGS to "" (nothing).
this is when i discovered the problem when trying to cdbs'ify
pd-arraysize, because the build would fail.
(never mind my cdbs'ifying that; i'm trying to build a common
cdbs-snippet for more easy packaging in debian)

i'm really not trying to use autotools here, as that is definitely an
overkill in most situations.
however, afaict, CFLAGS and LDFLAGS are commonly meant to be settable by
the user, so setting those should not break the build system.


the problem also is not template Makefile centric (though i stumbled
over the problem with the template Makefile in this special case;
however, in the past, i have stumbled over this problem with other
Makefiles as well)
autotools will kind of automatically take care of those things, but
since this is such a common case, i do believe that there must be a
elegant, vanilla make solution for the problem.

i'm really not trying to invent problems but to solve them.
