[PATCH] powerpc: Installed-header hygiene

[Tulio Magno Quites Machado Filho]

Fix powerpc-specific headers:
 - Make it compatible to C89 by replace references to inline by __inline__.
 - Get the definition of sigset_t used by
   sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h.
 - Includes missing header file.

2016-09-27  Tulio Magno Quites Machado Filho  <tuliom@linux.vnet.ibm.com>

	* sysdeps/powerpc/sys/platform/ppc.h (__ppc_get_timebase): Replace
	inline by __inline__.
	(__ppc_yield, __ppc_mdoio, __ppc_mdoom, __ppc_set_ppr_med): Likewise.
	(__ppc_set_ppr_med_low, __ppc_set_ppr_low): Likewise.
	(__ppc_set_ppr_very_low, __ppc_set_ppr_med_high): Likewise.
	* sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h: Require
	sigset_t from signal.h.
	* sysdeps/unix/sysv/linux/powerpc/sys/user.h: Include stddef.h,
	which is already required.
