Chris, 

Firstly, thanks for all the x32 patches!

I tried to build gnu-efi for x32 via genericx86-64 and still got a
failure about missing the gnu/stubs-64.h. I am building pure x32, is it
possibly you build x32 in a TMPDIR that already had a 64bit build?

There is a generated stubs-x32.h, but not the required -64 variant.

Can you confirm this builds correctly?

Thanks

Sau!
