Meson fails to detect the dependencies that are included
in PKG_CONFIG_PATH and built for ppc64le if binaries.pkgconfig
is not set in the ppc64le cross-file for Ubuntu.
This fixes the issue by setting binaries.pkgconfig to the
binary provided by the package 'pkg-config-powerpc64le-linux-gnu'.

Why not adding the same for ppc64le-power8-linux-gcc?
+pkgconfig = 'powerpc64le-linux-gnu-pkg-config'
I didn't find any operating systems that distribute the powerpc64le
cross-
compiler with the binary names found in config/ppc/ppc64le-power8-linux-
gcc.
Both Ubuntu and Fedora use the -gnu suffix. Fedora doesn't seem to have
a pkg-config binary for powerpc64le though.
I am able to cross-compile dpdk on Ubuntu with the default config file

Hi Thinh,
I'm also able to cross-build for ppc64 on Ubuntu, but without setting
binaries.pkgconfig, meson will skip some build targets, even if
PKG_CONFIG_PATH points to their dependencies.
Have you tried on Fedora?
As Thinh points out, you can't cross-compile for ppc64le on Fedora with
distro supplied packages. Ran across this question about the issue
relative to ARM on the Fedora Project website:
https://ask.fedoraproject.org/t/cross-compiling-to-arm/17864/12
And also confirmed internally with our toolchain developers that you'd
need glibc support which isn't provided in the existing Fedora packages.
Consensus seems to be that Fedora cross-compile is for
kernels/bootloaders only, though I'd love to hear from someone at Red
Hat if I'm mistaken.
Ubuntu/Debian do support the functionality, so you could try those
environments (as used by Github Actions for DPDK commits), use a third
party toolchain such as those found on:
https://toolchains.bootlin.com/releases_powerpc64le-power8.html
Or you could use the IBM Advanced Toolchain for POWER:
