Call init_cpu_features only if SHARED is defined
In static executable, since init_cpu_features is called early from __libc_start_main, there is no need to call it again in dl_platform_init. [BZ #20072] * sysdeps/i386/dl-machine.h (dl_platform_init): Call init_cpu_features only if SHARED is defined. * sysdeps/x86_64/dl-machine.h (dl_platform_init): Likewise.
