Yann E. MORIN 3f6e5fb470 package/pkg-meson.mk: allow packages to add extra [binaries]
meson does not allow passing path to helper programs (e.g. pkgconfig)
using variables in the environment. Instead, it insists that those paths
be defined in the cross-compilation.conf file, in the [binaries]
section [0]

As such, allow packages to declare such a list of arbitrary entries to
add in the [binaries] section.

[0] https://github.com/mesonbuild/meson/issues/3327 for the LLVM_CONFIG
    example, which we'll address in a follow-up patch.

# Meson package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files for Meson packages. It should be used for all
# packages that use Meson as their build system.
#
# See the Buildroot documentation for details on the usage of this
# infrastructure
#
# In terms of implementation, this Meson infrastructure requires
# the .mk file to only specify metadata information about the
# package: name, version, download URL, etc.
#
# We still allow the package .mk file to override what the different
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
# already defined, it is used as the list of commands to perform to
# build the package, instead of the default Meson behaviour. The
# package can also define some post operation hooks.
#
################################################################################
#
# Pass PYTHONNOUSERSITE environment variable when invoking Meson or Ninja, so
# $(HOST_DIR)/bin/python3 will not look for Meson modules in
# $HOME/.local/lib/python3.x/site-packages
#
MESON = PYTHONNOUSERSITE=y $(HOST_DIR)/bin/meson
NINJA = PYTHONNOUSERSITE=y $(HOST_DIR)/bin/ninja
NINJA_OPTS = $(if $(VERBOSE),-v) -j$(PARALLEL_JOBS)

# inner-meson-package -- defines how the configuration, compilation and
