In general, I would prefer not to mark packages as unsupported on a
platform unless there is good reason to believe that the problems would
be very difficult to resolve.

In this case, Debian contains builds of mozjs for MIPS, and MIPS is
supported by the Mozilla project.  For example, see:

  https://bugzilla.mozilla.org/show_bug.cgi?id=902818

where a mozjs bug is reported on MIPS (N32 ABI) and later fixed by
upstream.

Furthermore, mozjs is an important package.  polkit depends on mozjs,
and several important GNOME components depend on polkit, so without
mozjs we cannot have GNOME on MIPS.

So, I would prefer to revert this commit.  What do you think?
