* linux-aarch64-low.c (aarch64_get_hwcap): Remove function.
(aarch64_arch_setup): Call linux_get_hwcap.
* linux-arm-low.c (arm_get_hwcap): Remove function.
(arm_read_description): Call linux_get_hwcap.
* linux-low.c (linux_get_auxv): New function.
(linux_get_hwcap): Likewise.
(linux_get_hwcap2): Likewise.
* linux-low.h (linux_get_hwcap): New declaration.
(linux_get_hwcap2): Likewise.
* linux-ppc-low.c (ppc_get_auxv): Remove function.
(ppc_arch_setup): Call linux_get_hwcap.
