specs whitespace intolerance

[Jim Wilson]

	In egcs-2.91.27, if the final blank line of the specs file
	is omitted, the compiler front end inserts a specious newline 
	in the back-end command line after the first argument, confusing
	exec and the back end.

I checked in this patch to fix it.

	* gcc.c (read_specs): Handle missing blank line at end of specs file.
