Thanks, I've committed this, please commit the cleanups.

Since ecl needs compiler support, the headers and libraries need to be
buildlink'ed in, so do that (include its buildlink3.mk file). But
since ecl's not needed at runtime (no shared libraries, right?) you
can set

BUILDLINK_DEPMETHOD.ecl=build

in the package including ecl/buildlink3.mk, before including that
bl3.mk file.
