BUG: Always pass linker flags untouched 

In cmComputeLinkInformation we recognize link options that look like
library file names, but pass flags starting in '-' through untouched.
This fixes the ordering of the check to recognize '-' flags first in
case the rest of the option looks like a library file name, as in the
case of "-l:libfoo.a".
