lang/gcc13-devel: Enable support for .init_array and .fini_array

Enable support for .init_array and .fini_array, which FreeBSD supports
since commit 83aa9cc00c2d83d05a0efe7a1496d8aab4a153bb in the src
repository.

There __FreeBSD_version is 1000009, so we start enabling the support
from __FreeBSD_version == 1000010.
