* use lexicographical ordering, as "gcc -march=foo" does
* correct usage of @samp vs @option, add @samp where appropriate
* add armv6k, armv6z, arm6zk -march option values
* remove -march=ep9312, it is only valid for -mcpu
* add armv6s-m and document it, as it is no official ARM name.
Support for the OS extension/SVC is mandatory, non-supporting
implementations are deprecated (ARMv6-M Architecture Reference Manual, B.2)
