I assume you mean

for Makefiles?

Because redirection won't happen after parameter expansion.
And sticking an `eval' before above line won't work either:
you lose your nice spaces/tabs and such in $LDDPOSTPROC due
to missing quotation.

Maybe you can settle on something like this use instead?

  $LDDPROG 2>/dev/null | $LDDPOSTPROC
or even
  $LDDPROG 2>/dev/null | $SED $LDDPOSTPROC

It should be possible to merge all the multiple-sed-pipes in ldd.m4
using multiple `-e' options; barring sed bugs, which I haven't checked
now (but for that, using $SED could help).
