Fixing cross-compilation 1/2

[Paul Millar]

Hi,

The patch fixes an existing test within the autoconf configure.ac.  The test
makes assumptions about the linker, which are wrong:
  1. for cross-compliation (MinGW linker doesn't go near /usr/X11R6/lib)
  2. under X11R7.0, the libraries have moved to /usr/lib (at least under 
Debian)

I'd be happy to just remove the test, but there may be some obscure users for
whom the information may be relevant.  I've kept the test, rewording it
slightly and downgraded it from an error to a warning.

This is a resubmission (no comment from previous submission) so please comment
if its wrong!

Cheers,

Paul.

ChangeLog:
  Downgrade configure test because it gets it wrong sometimes.
