dnl Generate the Makefile in a target specific directory.
dnl Substitutions aren't performed on the file in AC_SUBST_FILE,
dnl so this is a cover macro to tuck the details away of how we cope.
dnl We cope by having autoconf generate two files and then merge them into
dnl one afterwards. The two pieces of the common fragment are inserted into
dnl the target's fragment at the appropriate points.

dnl but always used by common/Make-common.in. So we have to subst here even
