Fix rendering with mandoc
Fix the negation (!) operator so that it binds only to the word that
immediately follows it, which means 'not' has to be reset every time an
option word or device name is processed.
Add ARMV6 as an arm option.  This will cause obscure magic in config(8)
to automatically set the armv6 option when MACHINE_ARCH is armv6.  That
allows replacing ever-growing lists of cpu names as options to compile
a given file with the using either "optional armv6" or "optional !armv6".
