This patch adds AArch32 support for -march=armv8.[78]-a.
The behaviour of the new options can be expressed using a
combination of existing feature flags and tables.
The cpu_arch_ver entries are technically redundant but
it seemed less surprising to include them anyway.
Tested on aarch64-linux-gnu. OK to install?
Richard

...which wouldn't count for much. Actually tested on arm-linux-gnueabi
and arm-eabi.
