Thomas Petazzoni 3d2810bdcf package/grpc: fix build on non-NPTL systems
uClibc-ng in non-NPTL configurations doesn't implement
pthread_setname_np(). Unfortunately grpc assumes that as soon as
__GLIBC__ is defined, pthread_setname_np() is available. It is
particularly sad, because grpc build system uses CMake, so it is
trivial to do such a check.

This commit adds a patch that does just this: check for the
availability of pthread_setname_np(), and use it only if
available. The patch has been submitted upstream.

Fixes:

Subject: [PATCH] Properly detect the availability of pthread_setname_np()
This commit adds a CMake check for the availability of
pthread_setname_np(), and only uses it on Linux when available.
Indeed, some C libraries, such as uClibc, do not provide this
non-POSIX function in all cases.
