Martin Storsjö f96d07f4ec configure: Add quotes around a variable which might be empty 
If we only have a target compiler but no host compiler, the $type
variable will be empty once.

(Currently we fail to do a cross build if no host compiler is available
due to using the host compiler for processing option lists though.
But despite that, this comparison in configure needs quotes.)
