Is dropping dashes from the variable uniformly correct? If so,
could you please clarify in the commit message why that is?
The target option requires the following format:
<arch><sub>-<vendor>-<sys>-<abi>
In other places, we need the trailing dash as GNU tools are using the same
format as above with a dash to separate the tool name.
