[PATCH] Arm: .noinit and .persistent are not supported for Linux targets

[Jan Beulich]

Respective tests being run means guaranteed failures.

fuchsia, haiku, nacl and phoenix look to be similarly affected, but
knowing nothing about those targets I don't think I should touch them.
Plus of course there's the obvious alternative of the respective
ld/emulparams/armelf_*.sh simply being wrong in not enabling one or both
of the features.
