AArch64 validation fails with many invalid relocations

Test ways requiring the RTS linker (e.g. ext-interp) are failing due to the assert(isInt64(32, addend)); assertion in the COMPAT_R_AARCH64_ADR_PREL_PG_HI21 of encodeAddendAarch64. One such relocation is,

RELOCATION RECORDS FOR [.text]:
OFFSET           TYPE              VALUE
000000000000001c R_AARCH64_ADR_PREL_PG_HI21  stg_upd_frame_info

although there are plenty of others.
