[Bug 1741996] [NEW] Undefined references to 64-bit division in libefi on 32-bit systems

[Matthew Garrett]

Public bug reported:

Building a 32-bit binary and linking against libefi.a gives the
following:

/usr/lib/libefi.a(math.o): In function `DivU64x32':
(.text+0x95): undefined reference to `__umoddi3'
(.text+0xaa): undefined reference to `__udivdi3'

Fedora carry this patch to avoid it:
