The output says

The related code in configure seems to be
------------------->snip<------------------
cat > conftest.c <<EOF
int _start (void) { return 0; }
int __start (void) { return 0; }
int foo (void) { return 1; }
int (*fp) (void) __attribute__ ((section (".init_array"))) = foo;
EOF
------------------->snip<------------------
But i've no idea what the real problem is. It looks like it's not related to the ".init_array" but to the missing `mcount' symbol.
