problem with ./configure

[BOUQUE Anais]

Hello,
I use autoreconf and configure, and I have a problem using configure : I use 
the cl6x compiler, (./configure --host=c6x CC=cl6x) but when configure does 
"cl6x -version" or "cl6x-v" or "cl6x -V", there is an error, because the 
correct option to have the version of cl6x is "cl6x -version".

I use this Makefile.am:
bin_PROGRAMS=bonjour
bonjour_SOURCES= hello.c

And this configure.ac :
AC_INIT(hello, 0.1, address@hidden)
AM_INIT_AUTOMAKE(foreign)
AM_PROG_CC_C_O
AC_CONFIG_FILES([Makefile])
AC_OUTPUT

The hello.c is a very simple source code which prints "hello world" (this is 
just a test).

Here is the part of config.log with the error:
configure:1781: checking for c6x-gcc

Can I do something to solve that problem?
If you need more precise information, tell me, and I will send it to you.
Thanks for advance,
