I contacted the maintainer of the repo and asked them to add a tag,
which is done now.

Note: apparently the author re-released 098 with a hotfix very soon
after releasing it, without making a version change.  In the repository,
this is tagged as 098b, which I use here.  I.e. this is not a true
version update; we were already using "this 098".

More or less the same thing; it's sanctioned by the developers even
though it's acknowledged not to be a particularly good solution.  Here
we see Arch do the same:

(Though this one seems to have a bug because they copy things to
~/Emulation instead of the new ~/.local/share.  I'm confident that
~/.local/share is the right location in the latest release.  Also for
the cheats.bml file.)

Here's a patch that, in addition to switching the repo, adds a patch
removing a -march=native flag (which I assume would break
cross-compilation), and passes the make flag "profile=balanced" to make
higan less CPU intensive by emulating a bit less accurately (it was
running too slow on my i5, so this should be a better default).

I just saved a princess from an evil wizard with this so I can confirm
it runs smooth now.
