[RFA] Handle expected failure in interrupt.exp for Linux/x86

[RFA] Handle expected failure in interrupt.exp for Linux/x86

[Mark Kettenis]

Ouch!  Letting GDB call a function from an interrupted restartable
system call doesn't work on Linux/x86.  This already was an expected
failure.  Unfortunately it only deals with a SIGSEGV wheras a SIGILL
is just as likely.

Fixing the actual problem isn't easy.  I'll try to come up with
something clever.  In the meantime, I'd like to check in this patch.

OK?

Mark

	* gdb.base/interrupt.exp: Treat SIGILL similar to SIGSEGV such
	that we catch the expected failure under Linux/x86.
