The relocation type R_AARCH64_PREL32 in .rela.eh_frame (exception handling
frame) does not fit the checking requirement of GenFw in EDK2.
Building EDK2 with aarch64-elf bare metal toolchain (no unwind table by
default) will succeed. However build of EDK2 with aarch64-linux-gnueabi
toolchain (default enable unwind table generation) will fail.
EABI is closely tied to 32-bit ARM/AArch32, and so there is no such
thing as a 'aarch64-linux-gnueabi' compiler.
The issue can be fixed by adding -fno-unwind-tables, in order to disable
generating unwind table info, which is used mainly for debug. This commit
enables successful compilation of EDK2 both with aarch64-elf and
aarch64-linux-gnueabi toolchains.
This has nothing to do with bare metal vs hosted. Are you using the
RedHat build of GCC by any chance?
