Thanks, here's the relevant part of the config.log file, the result of the 
configure script trying to compile a very simple 
C program file containing a program that does nothing but return a program 
status:

  configure:4489: checking whether the C compiler works

It looks like Linux-specific flags (and possibly gcc-specific) compiler options 
are being used with xlc.  
In particular, the "--Wl," syntax used to pass options to the loader is not 
recognized by xlc.

It's possible that you have some environment variables set, such as CFLAGS, 
CPPFLAGS, LDFLAGS, LDLIBS, 
and others, that are not appropriate for xlc.  Other possibilities are that you 
have an alias for xlc that adds 
some of these options, or an xlc shell script in your path that invokes xlc 
with additional options.

Could you look at the environment variables you have set before invoking the 
configure script to see if they are
interfering with xlc?  The problem is whatever is causing these extra options 
to be passed to xlc ...
