stand: compile ia32 EFI loader with -malign-double

The UEFI spec says:
> Structures are aligned on boundaries equal to the largest internal
> datum of the structure and internal data are implicitly padded to
> achieve natural alignment.

By default, structs containing members of type "long long" have 4 byte
alignment on i386. This caused some EFI structures to be subtly wrong.

Fix this by compiling the ia32 EFI loader with -malign-double, which
bumps the alignment up to 8 if such members are present.
