Summary

The reason for this is to increase discoverability of MAKE_JOBS_UNSAFE.

Test Plan

HTML version renders just fine in the browser.

Fine for me.

Though, it might be nice to expand a bit, saying that the failures can be intermittent, or something.

@mat, how about something like:

It is used when a port is known to be broken with <varname>-jX</varname> due to race conditions causing intermittent build failures.

• Improve the description (as requested by @mat).
• Use <literal> instead of <varname> for options similarly to how --with-xxx is formated later on in the handbook.

Approved for commit. Thanks for reminding.
