TS-2382: sudo make install creates man files as root in build tree
Re-enable -Werror for developer builds

-Werror is supposed to be enabled by default during the development
cycle (see TS-1786). --enable--werror defaults to enabled if the
version ends in "-dev", but the "-dev" suffix was lost during the
last release cycle.
Remove the -dev again, we are not making any dev releases, and master is
always releasable and "stable". Lets figure out some other way of enabling
werror please.
