universal binaries for Mac

[Mojca M. <moj...@gm...>]

Hello,

There are no gnuplot binaries for 4.2 available yet (which would be
helpful for users to test), bet I guess that for Mac it would be
hepful to have universal binaries (to work both on PowerPc & Intel
processor) and I don't think that gnuplot currently takes care about
that.

Here are some notes:

Most importantly, this should be added:

CFLAGS
    -arch i386 -arch ppc
LDFLAGS
    -arch i386 -arch ppc

./configure ... --disable-dependency-tracking

The --disable-dependency-tracking option to configure causes it to not
use gcc's built-in dependency generation code, which does not work
with multiple -arch targets.
