AArch64: Add Linux cpuinfo string for rng feature
The Linux kernel has defined the cpuinfo string for the +rng feature, so
this patch adds that to GCC so that -march=native can pick it up.
Bootstrapped and tested on aarch64-none-linux-gnu.
gcc/
* config/aarch64/aarch64-option-extensions.def (rng): Add
cpuinfo string.
(cherry picked from commit 0d8f3f612d662ea3007c184a11ea5eb7d58760e7)
(cherry picked from commit 05c3a208a19af25fbfd5c7cad8be12e23bf84cfa)
