signal: Define __ARCH_HAS_SA_RESTORER so we know whether to clear sa_restorer
flush_signal_handlers() needs to know whether sigaction::sa_restorer is defined, not whether SA_RESTORER is defined. Define the __ARCH_HAS_SA_RESTORER macro to indicate this. Vaguely based on upstream commit 574c4866e33d 'consolidate kernel-side struct sigaction declarations'. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Cc: Al Viro <viro@zeniv.linux.org.uk>
