As per the tree file, the problem is that jwm has a recursive dependency on libGLESv2 pulled in by its direct dependency on librsvg.
In older versions of mesa, libGLESv2 did not need the rest of the mesa libraries, but it now does - see
https://forum.tinycorelinux.net/index.php/topic,27837.0.html.
It is possible that jwm could be re-built to not need librsvg or librsvg could be rebuilt to not need libGLESv2, which could solve the problem.
libGLESv2 was originally needed by cairo, but is no longer required by cairo, so it is possible that re-building librsvg might be the solution - I see that in x86_64, librsvg does not depend on libGLESv2.
I'll take a look at this in the next few days.
