On Fedora, the pcc64 cross-compiler is provided by package 'gcc-powerpc64le-linux-gnu' with binary names /usr/bin/powerpc64le-linux-gnu-*, same as in Ubuntu.
The cross-file config/ppc/ppc64le-power8-linux-gcc doesn't work with Fedora since the binary names in the file don't have the -gnu suffix, so I'm not sure where this cross-file is being used.
Another issue I found is that when I set the correct binary names in config/ppc/ppc64le-power8-linux-gcc or use config/ppc/ppc64le-power8-linux-gcc-ubuntu, I get the following error on Fedora:
config/ppc/meson.build:6:4: ERROR: Problem encountered: Only 64-bit compiles are supported for this platform type
It happens because cc.sizeof('void *') in https://git.dpdk.org/dpdk/tree/config/meson.build#n144 returns '-1'. I'm on Fedora 35.
Is anyone able to cross-build for ppc64le in Fedora?
