[OE-core] [PATCH] meson: map powerpc64 TARGET_ARCH to ppc64 for the cross file

[Victor Kamensky]

Meson uses 'ppc64' for 64 bit powerpc. Issue came up while
building systemd for MACHINE that uses ppc64e5500 tune.

BTW very nice diagnostic message through
https://wiki.yoctoproject.org/wiki/Meson/UnknownCPU, that led directly 
to the fix
