Subject: [PATCH] Several changes to fix musl build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

stress-{context, stackmmap}.c: Set tests to non-implemented because uses
swapcontext, musl provide the definition but not the implementation due
  to that functions are pre-POSIX and set to be deprecated.
  stress-{resources, pty}.c: Doesn't include termio.h and remove stress
  operations that uses struct termio, musl doesn't provide that struct.
stress-malloc.c: Check for definition of M_MMAP_THRESHOLD musl doesn't
  ptovide that constant.
stress-madvise.c: Add static poision_count integer, definition of
  MADV_SOFT_OFFLINE doesn't grauntee MADV_HWPOISON to be defined.
cache.c: Define GLOB_ONLYDIR not available on MUSL.
