Well yes.  Roland wrote GNU make, and glibc probably uses every single
feature of it.  Automake has little to no knowledge about GNU make-
specific constructs.

Can you off-load the sysdeps detection into a couple of configure macros
and replace the corresponding file names with AC_SUBST substitutions?
You'd still have to list all possible files in some EXTRA_libdfp_a_SOURCES
variable somewhere, but at least that would get you going.

Hope that helps for a start.
