Alpha was never relevant for the MS-Windows builds, either, but we
still had this code since about forever.

But my point was that I'm not sure this isn't needed for the GCC build
on Windows.  I don't know enough about how GNU ld generates MS-Windows
executables to tell whether this could be so.  If you feel strongly
about getting rid of those 2 lines, I guess it's okay to try that on
master.
