[PATCH v3 0/7] Improve core EAL musl compatibility

[Anatoly Burakov <anatoly.burakov@intel.com>]

This patchset fixes numerous issues with musl compatibility
in the core EAL libraries. It does not fix anything beyond
core EAL (so, PCI driver is still broken, so are a few other
drivers), but it's a good start.

Tested on container with Alpine Linux. Alpine dependencies:

build-base bsd-compat-headers libexecinfo-dev linux-headers numactl-dev

For numactl-dev, testing repository needs to be enabled:

echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories

If successful (using a very broad definition of "success"),
the build should fail somewhere in PCI bus driver in UIO.

v3 -> v2:
- Made _GNU_SOURCE unconditional for all DPDK targets
- Fixed usage of __USE_GNU and _GNU_SOURCE accross DPDK

v2 -> v1:
- Fixed patch 2 to use existing define if available
- Fixed patch 7 to use proper format specifier and
  cast pthread ID to unsigned pointer type
