Bug#203097: A better patch

[Daniel Schepler <schepler@math.berkeley.edu>]

Here's a patch I like better.  It implements calling debian/rules
build-arch if appropriate, but falls back to debian/rules build if
that target isn't present.  (According to policy, debian/rules does
have to return an exit code of 2 if it doesn't provide build-arch --
and this is automatically provided by make anyway.)  I've tested this
patch with packages with and without build-arch provided.
