Hi,

openjdk-11 FTBFS on mips* (and I expect others which have not built yet)
with this error:

This happens because the build system inserts a -m32 or -m64 option on
all architectures except arm*.

For Debian this can probably be removed completely, or at least changed
to whitelist the architectures this is supported on (these are the x86,
powerpc, s390 and sparc families I think). I've attached a patch which
does the latter.

Thanks,
James
