[PATCH 5.15 fix build id for arm64 0/5]

[Tom Saeger]

Build ID on arm64 is broken if CONFIG_MODVERSIONS=y
on 5.4, 5.10, and 5.15

I've build tested on {x86_64, arm64, riscv, powerpc, s390, sh}

Without these patches Build ID is missing for arm64 (ld >= 2.36):

  $ readelf -n vmlinux | grep "Build ID"

*NOTE* to following is not in mainline, yet:
[PATCH 5.15 fix build id for arm64 5/5] sh: define RUNTIME_DISCARD_EXIT
