Remove the section about universal binaries from macOS docs

Browse Source 
This is not relevant any longer, all supported macOS versions support
x86-64 binaries and the latest ones don't support anything else, so
there is no need to create i386 binaries any more (and PPC ones don't
work since ages).

Creating universal binaries {#osx_universal_bin}
---------------------------
The Xcode projects for the wxWidgets library and minimal project are set up
to create universal binaries.
If using the Apple command line tools, pass --enable-universal_binary when
configuring wxWidgets. This will create the libraries for all the supported
architectures, currently ppc, i386 and x86_64 . 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
binaries together. Assuming building on a PPC system:
1. First build in the usual way to get the PPC library.
2. Then, build for Intel, in a different folder. This time use:
export CFLAGS="-g -isysroot /Developer/SDKs/MacOSX10.7.sdk -arch i386"
export LDFLAGS="-syslibroot,/Developer/SDKs/MacOSX10.7.sdk"
./configure --disable-dependency-tracking --enable-static=yes --enable-shared=no \
--target=i386-apple-darwin8 --host=powerpc-apple-darwin8 --build=i386-apple-darwin8
You will need to reverse the powerpc and i386 parameters everywhere to build PPC on an Intel
machine.
3. Use lipo to glue the binaries together.
