I ran into the same problem.  This is not about -o and -s.  If you look
closely, you will notice a lonely LinuxMachineDefines in the command line,
which egcs is taking to be some file to link or something...

The problem can be tracked down to cpp that no longer defines i386 and/or
__alpha, depending on your architecture.

The proper fix is probably to patch the imakedep.h file in the XFree86
distribution somewhat like the following patch, and recompile XFree86:

--- XFree86-3.3.2.3/xc/config/imake/imakemdep.h.dist    Sun Jul 27 04:41:05 1997
+++ XFree86-3.3.2.3/xc/config/imake/imakemdep.h Mon Sep  7 12:15:49 1998

But you can also get around the problem by hacking the
/usr/X11R6/lib/X11/config/linux.cf file.

HTH.  Cheers,
