build/pkg-config: improve static linking flags

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.

examples: hide error for missing pkg-config path flag

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.

examples: fix build with old 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.

examples: detect default build directory

Most examples have in their makefiles a default RTE_TARGET directory to be
used in case RTE_TARGET is not set. Rather than just using a hard-coded
default, we can instead detect what the build directory is relative to
RTE_SDK directory.

This fixes a potential issue for anyone who continues to build using
"make install T=x86_64-native-linuxapp-gcc" and skips setting RTE_TARGET
explicitly, instead relying on the fact that they were building in a
directory which corresponded to the example default path - which was
changed to "x86_64-native-linux-gcc" by commit 218c4e68c1d9 ("mk: use
linux and freebsd in config names").

mk: use linux and freebsd in config names

Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e. both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"
work.

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.
