Allow passing the list of architectures to --enable-universal_binary.

Browse Source 
Interpret --enable-universal_binary argument as a comma-separated list of
architectures to use. By default still use all the supported ones.

to create universal binaries.
If using the Apple command line tools, pass --enable-universal_binary when

you need to add -arch ppc -arch i386 to your CFLAGS.
configuring wxWidgets. This will create the libraries for all the supported
architectures, currently ppc, i386 and x86_64 when using Cocoa (Carbon isn't
available in 64 bit builds). You may explicitly specify the architectures to
use as a comma-separated list, e.g. --enable-universal_binary=i386,x86_64.
Notice that if you use wx-config --libs to link your application, the -arch
flags are not added automatically as it is possible to link e.g. x86_64-only
program to a "fat" library containing other architectures. If you want to
build a universal application, you need to add the necessary "-arch xxx" flags
to your project or makefile separately.
As an alternative to using --enable-universal_binary, you can build for
each architecture separately and then use the lipo tool to glue the
