	* adaint.c Add file macro definitions missing on Android.
	* adaint.h Avoid definitions related to task affinity and CPU
	sets since this functionality is missing on the Android
	* errno.c (__set_errno): Android already contains such a named
	procedure so do include again.
	* gsocket.h: Sockets not supported on Android.
	* init.c: Avoid linux related code not supported on Android.
	* sysdep.c (sigismember, sigaddset, sigdelset, sigemptyset,
	sigfillset): wrapper functions since sig routines are defined
	as inline macros on Android.
	* terminals.c: Add stubs for terminal related functions not
	supported on Android.
