Comment (by mojca@…):

 One of the problems with current patch is that it skips this test:
 {{{
     if echo $OSX_ARCH_OPTS | grep -q ","; then
         AC_MSG_WARN([Disabling dependency tracking due to universal binary
 build.])
         disable_macosx_deps=yes

         dnl HACK: PCH could be made to work by precompiling for each
 architecture into separate directories
         dnl and including all architecture directories with each compiler
 invocation.
         dnl That would require a major rework of Bakefile and at the same
 time it would be nice to have
         dnl Objective-C++ precompiled headers.
         AC_MSG_WARN([Disabling precompiled headers due to universal binary
 build.])
         bk_use_pch=no
     fi
 }}}
 and possibly some other places like:
 {{{
     AC_MSG_CHECKING([for architectures to use in universal binary])
     AC_MSG_RESULT([$OSX_ARCH_OPTS])

     dnl NOTE: Only the compiler driver needs arch flags.  The link editor
     dnl is incapable of using them but the compiler driver (which we use
     dnl as LD when building dynamic libraries) uses them to invoke the
     dnl real ld multiple times.  If we moved to libtool -dynamic we would
     dnl need no arch flags because libtool automatically invokes ld for
     dnl every architecture found in the fat input files.
     dnl
     dnl For static library builds, AR/RANLIB automatically create proper
     dnl fat archives although AR is unable to update them once RANLIB has
     dnl made them into proper fat archives.  Fortunately, our link process
     dnl simply removes the .a file before using ar to create a new one.
     dnl If we did move to libtool -static we still wouldn't need arch
 flags
     dnl because libtool automatically figures it out based on input.
     retest_macosx_linking=yes
 }}}
 because it sets {{{OSX_ARCH_OPTS}}} to {{{-arch i386 -arch x86_64}}}
 instead of {{{i386,x86_64}}}.

 It would be a lot cleaner to specify the flags in command line rather than
 patching {{{OSX_ARCH_OPTS}}} in configure script. Apart from this there is
 another patch for {{{install_name_too}}}, but I don't understand that one.
