musl has always supported ELF-TLS anywhere except in libc itself. That
was also never the problem. The problem was that the mesa people select
the initial-exec TLS model explicitly, even though libGL ends up being
dlopen()ed quite often, and then you should be using the general-dynamic
model instead.
According to [1], Rich proposed dropping the initial-exec attribute and
replacing it with -mtls-dialect=gnu2 eight years ago. Has that happened
yet? If so, dlopen()ing libGL with musl ought to work.
Ciao,
