Take out all that extraneous whitespace.  Whitespace _IS_
significant, especially at the end of text sections.

In particular, the whitespace right before the last paren, outside of
the strip function, is definitely screwing things up; the expansion
would be something like:

  ifeq (linux,linux )

Well, "linux" is not equal to "linux ", so they don't match.
