I think this is caused by ‘includes/linux.inc’, which is unconditionally
included by default.

Disabling the line

    include includes/$(BLD_PLATFORM).inc

should be sufficient to fix this.

Alternatively, we could set BLD_PLATFORM (to something other than just
“linux” on non-x86_64) and patch “include” to read “-include”, so that
it doesn’t cause an error when the file does not exist.

That’s what the attached patch does.
