glibc added support for DT_GNU_HASH in 2006 and DT_HASH has been

Many vDSOs support DT_GNU_HASH. This patch adds selftests support.

Ping.
Some context: I'd change LoongArch vDSO to use the toolchain default
instead of forcing DT_HASH (note that LoongArch is launched decades
after all major distros switched to DT_GNU_HASH), but without the
selftest support we'll lose test coverage.
And now ARM64 has already lost test coverage after commit 48f6430505c0.
I am seeing several checkpatch errors - please fix them and send me v2.

Other checkpatch.pl output is not actionable. `ELF(Sym) *sym` instead

elsewhere ElfW in the code base).
Okay. Send v2 with the actionable change.
