It's a libtool bug, imho.  It should require both --tag and --mode for
all invocations, and not try to guess what the user wanted.

Are you running ccache or distcc (or have otherwise set CC to something
other than "cc" or "gcc")?  That's usually what causes it for me. 
Here's my fix, which will make it use the CC tag if its guess failed.
