The variables DPDK_MESON_OPTIONS, PATH, PKG_CONFIG_PATH,
CPPFLAGS, CFLAGS and LDFLAGS can be customized in the config file
loaded by devtools/load-devel-config at each build.
The configuration can be adjusted per target thanks to the value set
in the DPDK_TARGET variable.
PKG_CONFIG_PATH is specific to each target, so it must be empty
before configuring each build from the file according to DPDK_TARGET.
Inheriting a default PKG_CONFIG_PATH for all targets does not make sense
and is prone to confusion.
DPDK_MESON_OPTIONS might take a global initial value from environment
to customize a build test from the shell. Example:
DPDK_MESON_OPTIONS="b_lto=true"
Some target-specific options can be added in the configuration file:
DPDK_MESON_OPTIONS="$DPDK_MESON_OPTIONS kernel_dir=$MYKERNEL"

v2:
- unset PKG_CONFIG_PATH because empty is printed by meson
- add more comments
