Some more info.
This is where i get the error

echo "$as_me:$LINENO: checking for main in -lm" >&5
echo $ECHO_N "checking for main in -lm... $ECHO_C" >&6
if test "${ac_cv_lib_m_main+set}" = set; then
  echo $ECHO_N "(cached) $ECHO_C" >&6
else
  ac_check_lib_save_LIBS=$LIBS
LIBS="-lm  $LIBS"
if test x$gcc_no_link = xyes; then
  { { echo "$as_me:$LINENO: error:  Link tests are not allowed after 
GCC_NO_EXECUTABLES." >&5
echo "$as_me: error:  Link tests are not allowed after 
GCC_NO_EXECUTABLES." >&2;}
   { (exit 1); exit 1; }; }
fi
cat >conftest.$ac_ext <<_ACEOF
#line $LINENO "configure"
/* confdefs.h.  */
_ACEOF
cat confdefs.h >>conftest.$ac_ext
cat >>conftest.$ac_ext <<_ACEOF

and more specifically *
*if test x$gcc_no_link = xyes; then


Thanks in advance!
