The example app makefiles contained sections using the legacy method of
compiling with make. These are no longer needed, and are removed,
leaving only the section that uses pkg-config for the make build.

Rather than setting -Bstatic in the linker flags when doing a static link,
and then having to explicitly set -Bdynamic again afterwards, we can update
the pkg-config file to use -l:libfoo.a syntax to explicitly refer to the
static library in question. Since this syntax is not supported by meson's
pkg-config module directly, we can post-process the .pc files instead to
adjust them.
Once done, we can simplify the examples' makefiles and the docs by removing
the explicit static flag.

Fix the time of check time of use warning in example code.
Ignore the errno of unlink failure. There are two situations.
The first one is that file doesn't exist the unlink fails and
it's ok to ignore. The second one is that unlink fails to remove
file but the next bind() would fail too.

Some versions of pkg-config don't support the --path flag, which is not a
fatal error when building the apps. Without the flag, the makefile just
cannot track the .pc file of DPDK as a dependency of the build. Therefore,
we can ignore the error and suppress it by redirecting to /dev/null the
stderr from that call to pkg-config.

Not all versions of pkg-config in distros have support for the
--define-prefix flag [1], causing errors when building examples manually or
with test-meson-builds.sh script [2].
For the former case, we need to remove the hard-coded use of the flag in
the Makefiles.
For the latter case, the flag is necessary for builds to succeed, so we
skip the tests when it's not present, passing it as part of the pkg-config
command if it is supported.
