2f03f796a4 OvmfPkg: VirtioBlkDxe: fix div & mod of 64-bit dividends on IA32/gcc-4.4
OvmfPkg/VirtioBlkDxe/VirtioBlk.c:667: undefined reference to `__umoddi3'
OvmfPkg/VirtioBlkDxe/VirtioBlk.c:750: undefined reference to `__udivdi3'

These operations would come from libgcc in the IA32 build, but OVMF does not
link against libgcc.

Regression-tested the X64 build with Fedora 18 Alpha XFCE and Windows 8
Consumer Preview guests.
