[build] Fix ARM32 EFI builds with current EDK2 headers

Browse Source 
EDK2 commit 6440385 ("MdePkg/Include: Add enumeration size checks to
Base.h") enforced the UEFI specification mandate that enums should
always be 32 bits.  This revealed a latent bug in iPXE, which does not
build with -fno-short-enums.

Fix by adding -fno-short-enums to CFLAGS for ARM32 EFI builds.
