This is a binutils (ld) problem, not a GCC problem. But since your GCC is 9 years old, presumably your binutils are equally old and therefore unsupported.

Please update to a supported (by upstream) version of GCC and binutils. GCC 4.8 isn't even supported by the GCC people anymore, see top of https://gcc.gnu.org/gcc-4.8/ - (This release series is no longer supported.)

Also this check in configure was added only for Solaris support, __start_* and __stop_* symbols should really work on all other OS and since Solaris support was removed this check is vestigial and should probably be removed too.
