Hi Mike:

You had me going for a while. My comments on that collided with yours so I
abandoned mine, and I am just glad you were finally able to replicate the bug
(duplicate bad flag) I find now for the same configuration file that you are
using.  Also, for me the same ("flag flag" instead of "-Xlinker flag") bug
appears for me if I specify -L-Xlinker -L-flag on the command line.  Finally, I
notice JinShil has a one-line fix which I am about to test.
