The Fortran directories should be searched within the sysroot when there 
is one (the same conditions under which such C directories are searched 
within the sysroot).

By "lib{,<qual>}" do you mean lib/$(gcc -print-multi-os-directory) ?  
(Inventing yet another system for distinguishing multilibs, when there's 
already -print-multi-directory and -print-multi-os-directory, seems like a 
bad idea.)
