The get_ppc64_abi is used to determine the ELF ABI (i.e. V1 or V2). This routine is currently implemented in the linux-user/elfload.c file but is useful in other scenarios. Move the routine to a more generally available location (linux-user/ppc/target_cpu.h). Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
