[tex-live] dvipsk/squeeze and cross-compilation

[Olaf Weber]

squeeze is a little program that is compresses PS headers and is not
installed.  When cross-compiling, it needs to be treated differently.
I believe the following changes for dvipsk do the trick, even if they
are less than squeaky clean.  Change 5396 does the actual work, change
5397 checks in the updated configure script.

This as an example of how the cross-compilation support I added works
in practice.

Change 5396 by olaf at olaf on 2004/07/04 14:27:07

        dvipsk/Makefile.in, dvipsk/configure.in: squeeze must be compiled
        for the build machine when cross-compiling.  These changes should
        do the trick, in combination with regenerating configure.
