Build failure on musl since version 10.0

[ffontaine]

Build on musl is broken since version 10.0 because the include on config.h was removed from backtrace.h by 1544abf:

In file included from /home/buildroot/autobuild/instance-3/output-1/build/apitrace-10.0/thirdparty/libbacktrace/testlib.c:40:
/home/buildroot/autobuild/instance-3/output-1/build/apitrace-10.0/thirdparty/libbacktrace/backtrace.h:53:10: fatal error: gstdint.h: No such file or directory

      |          ^~~~~~~~~~~

I'll not send a PR as it should not affect master because of b1c99db

It's not clear if this was this was a transitory upstream bug? Or a mistake due to hand merging of 1544abf?

Either way, I'd rather not maintaining stable point releases, which cherry-picked changes. What I can do is release another major release in the near future. It's less work.

[ffontaine]

Do you still plan to release a new major release?

@ffontaine you're not alone who needs it: #784

[jrfonseca]

Done. Sorry for the wait
