New submission from Matthias Klose:
LIPL has the value
${prefix}/lib/python3.5/config-$(VERSION)$(ABIFLAGS)-x86_64-linux-gnu
and the code relies to substitute parameters from the left to the right, but it
prefers $() variables. the attached patch substitutes all variables from the
left to the right.
