    Fix "`gcc_struct' attribute directive ignored" warnings

    Compilation for target architectures other than i386, x86_64 or PowerPC
    (e.g. ARM) caused multiple warnings like the following to appear:

      doomdata.h:75:1: warning: ‘gcc_struct’ attribute directive ignored
       } PACKEDATTR mapsidedef_t;
       ^

    This was due to 'gcc_struct' being undefined for these architectures.
    Since that attribute was actually introduced by commit 87db726b9a9ae61ca
    to address the fact that -mms-bitfields became the default for GCC on
    Windows, limit it to that case.
