hunspell: no need for autoreconf when not patching configure

Also fix some bitrot... The LIBS statement was only active for the
autoreconf call, while where it would have mattered is the configure
call itself. Since it was built wihout those for all the time, delete
it.

also no need for explicit shell call, as it is by default executed in a
shell.

also fix missing comma in if statement for ENABLE_OPTIMIZED.
