fix signals tests

fix signals tests

[Bart Veer]

This patches signal1.c to only test abort() if there is a real
implementation of that function, and patches both tests to cope with
configurations that don't use main().

	* tests/signal1.c: skip the abort() test if there is no proper
	implementation.
	
	* tests/signal1.c, tests/signal2.c: allow to run if
	CYGPKG_LIBC_STARTUP is absent.
