It might be slightly more complex than this. gcc is ugly in that the
compile task executes a ton of separate configure processes and it could
be tripping up on the above expression on any one of those config.log
files.

Once you find the config.log, report back on which one it is and what
the message says and then we can work through how to fix it.

Cheers,
