I just did a quick look on the module because I do not have an urgent 
need for it, so this is just a little nitpick:

     string(REGEX REPLACE ";" "\\\\;" _C_MULTILIBS "${_C_MULTILIBS}")
     string(REGEX REPLACE "\n" ";" _C_MULTILIBS "${_C_MULTILIBS}")

Those can easily be written without REGEX, which will reduce the amount 
of backslashes.
