* configure.in: check availability of siginterrupt.

Browse source 
* scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
	HAVE_RESTARTABLE_SYSCALLS.
	(scm_init_scmsigs): use siginterrupt if it's available.  not
	everyone who has restartable syscalls has SA_RESTART it seems.
	(scm_sigaction): use scm_num2long/scm_long2num when converting
	SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM.  use
	scm_integer_p to test the type.
