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.

There is no need to check for each library, driver and example whether
certain cflags are supported. Instead of checking inside the loop, do
so outside and reuse the value.

The following error hits if host cc compiler is clang(default one in most
linux distributions) and the cross compiler is gcc.
The root cause is: the hybride compilers add the warning options to the
meson project as project arguments, which apply for both host compiling and
cross compiling. But some options such as '-Wno-format-truncation' are not
supported nor recognized by clang, so they have to be removed from the
project arguments for the host compiler to run smoothily and added back as
cflags for the cross compiler to compile for cross source files.
The fix is remove unrecognized warning options from the meson project
arguments shared by gcc and clang, as add them specifically for gcc or
clang as cflags.

When a required library is missing on a platform, rather than having
meson report an error about the missing variable, catch the problem
earlier and provide a more readable message.

To test building all relevant example applications as part of a build, we
add support for the "all" keyword to be passed to the "examples" build
option. Since not all examples can actually be built on all systems,
we also add support for the "build" option inside the sub-dirs. However,
in case where "all" is not used, and a particular example is requested
to be built, we will error out if building the requested app is not
possible.

The binaries and apps in DPDK all need to be linked against the
execinfo library on FreeBSD so add this as a dependency in cases
where it is found. It's available by default on BSD, but not
at all on Linux

Any flags added to the project args are automatically added to all builds,
both native and cross-compiled. This is not what we want for the -march
flag as a valid -march for the cross-compile is not valid for pmdinfogen
which is a native-build tool.
Instead we store the march flag as a variable, and add it to the default
cflags for all libs, drivers, examples, etc. This will allow pmdinfogen to
compile successfully in a cross-compilation environment.

This patch changes the build process to group all .o files for a driver or
library into a static archive first, and then link the .o files together
into a shared library. This eliminates the need for separate static or
shared object builds when packaging, for instance.
The "default_library" configuration option now only affects the apps and
examples, which are either linked against the static or shared library
versions depending on the value of the option.

Add support for having selected example apps built as part of a meson,
ninja build. By default none are built, and those to be built should be
named directly in the -Dexamples='' meson configuration argument.
This is useful for developers working on a feature who want to use a
suitable example, or examples, to test that feature, as they can compile
everything up in one go, and run the example without having to do a ninja
install first.
This commit adds examples which don't consist of multiple apps in
subdirectories to the meson build, so they can be built by default by
passing -Dexamples parameter to meson.
Not included are the following examples:
* ethtool
* multi-process
* netmap_compat
* performance-thread
* quota_watermark
* server_node_efd
* vm_power_manager
To test the apps added here, use the following command, merged to one line,
to add them to your meson build (command to be run inside the build
directory):
meson configure -Dexamples=bbdev_app,bond,cmdline,distributor,\
eventdev_pipeline_sw_pmd, exception_path,helloworld,\
ip_fragmentation,ip_pipeline,ip_reassembly, ipsec-secgw,\
ipv4_multicast,kni,l2fwd-cat,l2fwd-crypto,l2fwd-jobstats,\
l2fwd-keepalive,l2fwd,l3fwd-acl,l3fwd-power,l3fwd-vf,l3fwd,\
link_status_interrupt,load_balancer,packet_ordering,ptpclient,\
qos_meter,qos_sched,rxtx_callbacks,skeleton,tep_termination,\
