5d7b673d5f mk: build with _GNU_SOURCE defined by default
We use _GNU_SOURCE all over the place, but often times we miss
defining it, resulting in broken builds on musl. Rather than
fixing every library's and driver's and application's makefile,
fix it by simply defining _GNU_SOURCE by default for all
builds.

Remove all usages of _GNU_SOURCE in source files and makefiles,
and also fixup a couple of instances of using __USE_GNU instead
of _GNU_SOURCE.

803ee2ebd3 examples/performance-thread: fix return type of threads
The function pthread_create() expects void *(*func) (void *)
for function pointer, however, lthread_func_t was defined as
void (*func) (void *), so now gcc 8.1 warns that the cast is
incorrect, causing a compilation failure. This patch changes
the declaration of lthread_func_t from returning a void to
returning a void*, and then changes the sample app in the
relevant places that are affected by the typedef change.

842ee032e4 examples/performance-thread: check thread creation
There was a call for thread create function without result check.
Added result check and message printout after failure.

4cde45f36f examples/performance-thread: fix build on FreeBSD
This set of sample apps did not compile on FreeBSD due to use of a number
of Linux/glibc-specific APIs, or APIs which existed in different headers
on FreeBSD. Specifically, the following APIs has problems:
  * sched_getcpu() is a glibc extension, so use rte_lcore_id() on BSD
  * pthread_yield() returns int on Linux, but void on FreeBSD, so
    we have to create two slightly different copies of the function.
  * the type for managing cpu sets is cpuset_t on FreeBSD rather than
    cpu_set_t as on Linux, so use rte_cpuset_t from rte_lcore.h.
  * APIs for managing cpu affinity are in pthread_np.h on FreeBSD, rather
    than in pthread.h, also fixed by including rte_lcore.h

50810f095a config: remove useless explicit includes of generated header
The file rte_config.h is automatically generated and included.
No need to #include it.

The example performance-thread needs a makefile fix to avoid
overwriting the default cflags.

de186103da examples/performance-thread: fix return sign
The patch fixes an inverted return value in the
cond_destroy and cond_init APIs of the pthread shim
example.

These APIs are now demonstrated in the sample app by
having the mutexes and condition variables
explicitly destroyed before the appplication terminates.
