KVM: arm64: nVHE: gen-hyprel: Skip R_AARCH64_ABS32

Browse source

Ignore R_AARCH64_ABS32 relocations, instead of panicking, when emitting
the relocation table of the hypervisor. The toolchain might produce them
when generating function calls with kCFI to represent the 32-bit type ID
which can then be resolved across compilation units at link time.  These
are NOT actual 32-bit addresses and are therefore not needed in the
final (runtime) relocation table (which is unlikely to use 32-bit
absolute addresses for arm64 anyway).
