We currently permit R_ARM_GOT_PREL relocations in the ELF32 conversion routines, under the assumption that relative relocations are fine as long as the section layout is the same between ELF and PE/COFF. However, as is the case with any proxy generating relocation, it is up to the linker to emit an entry in the GOT table and populate it with the correct absolute address, which should also be fixed up at PE/COFF load time. Unfortunately, the relocations covering the GOT section are not emitted into the static relocation sections processed by GenFw, but only in the dynamic relocation section as a R_ARM_RELATIVE relocation, and so GenFw fails to emit the correct PE/COFF relocation data for GOT entries. Since GOT indirection is pointless anyway for PE/COFF modules running in UEFI context, let's just drop the references to R_ARM_GOT_PREL from GenFw, resulting in a build time failure rather than a runtime failure if such relocations do occur.
