Subject: [PATCH] jdk: disable backtrace() (musl build fix)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

musl doesn't implement / provide backtrace() and friends or
the corresponding header files. This is all glibc specific.

Use appropriate #ifdef to disable their use on musl and thus
to fix the build on musl.
