[build] Disable position-independent code for ARM64 EFI builds
Some versions of gcc (observed with the cross-compiling gcc 9.3.0 in
Ubuntu 20.04) default to enabling -fPIE. Experimentation shows that
this results in the emission of R_AARCH64_ADR_GOT_PAGE relocation
records for __stack_chk_guard. These relocation types are not
supported by elf2efi.c.
Fix by explicitly disabling position-independent code for ARM64 EFI
builds.
