Add sysdeps/x86/dl-procinfo.c
linux/x86_64/dl-procinfo.[ch] includes i386 dl-procinfo.[ch] when
building ldconfig since sysdeps/x86_64/dl-procinfo.c doesn't support
ldconfig.  Add sysdeps/x86/dl-procinfo.c to support ldconfig.  This
also removes the unnecessary _dl_procinfo from x86-64 ldconfig.  No
code changes in i686.  No code changes in x86-64 libc.so and libc.a.

	* sysdeps/i386/dl-procinfo.c (_SYSDEPS_DL_PROCINFO_C): New.
	(_dl_x86_cpu_features): Removed.
	Include <sysdeps/x86/dl-procinfo.c>.
	* sysdeps/unix/sysv/linux/x86_64/dl-procinfo.c: Removed.
	* sysdeps/unix/sysv/linux/x86_64/dl-procinfo.h: Likewise.
	* sysdeps/x86/dl-procinfo.c: New file.
	* sysdeps/x86_64//dl-procinfo.c (_SYSDEPS_DL_PROCINFO_C): New.
	(_dl_x86_cpu_features): Removed.
	Include <sysdeps/x86/dl-procinfo.c>.
