pkg-config is used outside of a libtool context too.

You can't solve the whole problem in libtool.  I was merely saying
that pkg-config upstream and in Debian now has the necessary patches,
but they will stay disabled until sarge releases; I wasn't talking
about libtool at all.

--as-needed is more or less just a way to hide errors and should
really be renamed to --print-unneeded or something similar where it
would generate warnings for unused libraries.
