Subject: [PATCH] patch(1) problems workaround

	. NUL input in 2 source files cause patch(1)
	  to truncate the input (and fail the patches); a sed
	  command removes the NULs
	. in binutils/ld, configdoc.texi is patched to be removed
	  but some patch(1)es leave an empty file, causing build problems;
	  this file is explicitly removed.
