Why is this file presence check needed?

Because, some of the examples are compiled under HAVE_xxx condition.

See the extract of examples/Makefile.am below.

	noinst_PROGRAMS = listdevs xusb fxload hotplugtest testlibusb
	
	if HAVE_SIGACTION
	noinst_PROGRAMS += dpfp
	
	if THREADS_POSIX
	dpfp_threaded_CFLAGS = $(AM_CFLAGS)
	noinst_PROGRAMS += dpfp_threaded
	endif
	
	sam3u_benchmark_SOURCES = sam3u_benchmark.c
	noinst_PROGRAMS += sam3u_benchmark
	endif

All Buildroot libcs support sigaction. Also, libusb depends on threads 
support, so THREADS_POSIX is always true in Buildroot.

So I think this check is not needed.

Okay, I will send a v2 without this check.
