[PATCH] configure: $x_includes used even if not set

[Rainer Müller]

Hi,

I am the maintainer for vim in MacPorts. The configure script triggered
a linking error for _Xsetlocale for us on Mac OS X. Here is a patch
which adds a conditional to make sure this test is not run if the
x_includes variable is actually not set.

Regards,
Rainer
