One random thing to consider that is GCC related. For FreeBSD 12.0
and later we are planning to use init_array and fini_array instead of
ctors/dtors for lists of constructor and destructor functions. clang
in head has already been changed to do this, and I've patched the
external toolchain versions of GCC in devel/*-gcc and base/gcc to do
this. lang/gcc* should also probably be patched with a similar patch
to what I used in base/gcc to enable it based on OSVERSION:
