Looking at config.log, this looks like a Libtool issue. Out of the
following:
-xtarget=opteron -xarch=amd64
it only passed "-xtarget" (it stripped off "=opteron" and didn't pass
"-xarch=amd64" at all).
I'm guessing what the French in your message says, but as a workaround,
if you need those two flags in your wrapper compilers, you might
consider setting them to be part of the compiler environment variable.
For example:
setenv CC "cc -xtarget=opteron -xarch=amd64"
and so on.
