Check for SA_RESTORER definition in <asm/signal.h>
Kernel header <asm/signal.h> cannot be included from regular code
because it conflicts with libc headers, but SA_RESTORER is needed in
signal.c, so SA_RESTORER value is forwarded from <asm/signal.h> to
config.h using a configure check.
* configure.ac (ASM_SA_RESTORER): Define if SA_RESTORER is defined
in <asm/signal.h>.
