bitbake.conf: set READELF for cross compilation

Browse Source 
In the case of using an external toolchain that supports multilib
compilation with a single binary, TARGET_PREFIX is the same for both main
and multilib abis. Without READELF exported, python3 assumes it is
either the readelf for ${BUILD_SYS}-readelf. Exporting cross readelf
fixes the build issue.
