[PATCH v2] Xmd.h: Treat __ILP32__ targets as LONG32 ones

[Sergei Trofimovich]

amd64-x32 ABI defines sizeof(long) == sizeof (void*) == 4

Noticed on build failure of libXmu:
  libXmu-1.1.0/work/libXmu-1.1.0/src/EditresCom.c: In function '_XEditresGetStringValues':
  libXmu-1.1.0/work/libXmu-1.1.0/src/EditresCom.c:2198:6: error: duplicate case value
  libXmu-1.1.0/work/libXmu-1.1.0/src/EditresCom.c:2194:6: error: previously used here

Change since v1:
- x32 got __ILP32__ and _ILP32 defines
  allowing result be more generic
