autoconf.info mentions the word "driver" just twice,
and not in regards to LD/LDFLAGS.
automake.info only knows drivers with "test drivers"
otherwise does not use the term.

I guess you meant -flto / -flto=auto.

Quite the contrary. The very same make manual you are citing is also
is *very explicit* about that LDFLAGS is *not* exclusively for
compilers/drivers:
| use 'LDFLAGS' in any compilation
| command that does linking as well as in any direct use of 'ld'.

I have seen traces of "CCASFLAGS" in automake, so I guess someone thought of
that already. And that would speak towards getting a CCLDFLAGS variable.
