>Description:
Not long ago, CPPFLAGS support was added to bsd.port.mk. Strange
thing, though, is that LDFLAGS support was not added along with it,
as these two options are usually used/changed together.

Handling them both will make it possible to remove CONFIGURE_ENV=
lines from many ports, which is good as those are error-prone hacks
(common mistage is CONFIGURE_ENV=LDFLAGS+=...), and will also allow
more flexibility, which we may need soon as new LTO-capable compilers
may require certain linker-only options and an ability for the user
and/or ports system to change them.
