Fixup for this line:

	WIRINGPI_SITE = $(call github,ciclonite,wiringPi,$(WIRINGPI_VERSION))

and the following is missing:

	$(eval $(autotools-package))

but build failed with
	config.status: error: cannot find input file: `Makefile.in'

in the base directory, maybe a autoreconf/configure/make in the
subdirectory wiringPi works?

I think a previous build was aborted while the package host-gawk was build, the patch was already
applied, but before the file 'output/build/host-gawk-4.1.2/.stamp_patched' was written...

Best way is to call clean for this package, eg.:

	$ make host-gawk-dirclean

or by hand:

	$ rm -rf output/build/host-gawk-4.1.2
