Comment (by jeremyhu@…):

 It looks like this goes back to the GPL2 versions, and assuming it hasn't
 changed in the mean time, we should be able to add this verbatim:

 {{{
 #if !defined(USED_FOR_TARGET) && defined(__APPLE__)
 #undef SIZEOF_LONG
 #if __LP64__
 #define SIZEOF_LONG 8
 #else
 #define SIZEOF_LONG 4
 #endif
 }}}

 to each of:

 gcc/config.in:#undef SIZEOF_LONG
 libcpp/config.in:#undef SIZEOF_LONG
 libdecnumber/config.in:#undef SIZEOF_LONG
 libgomp/config.h.in:#undef SIZEOF_LONG
