An update[1]. It seems that --disable-tm-clone-registry is the option that
results in crtbegin.o having a zero sized .init_array. I can't really follow
crcstuff.c but I see USE_TM_CLONE_REGISTRY in the context of .init_array so
something is happening when tm-clone-registry is disabled.

Yes that does the trick. I'll work on plumbing that into ct-ng when building
GCC 10 or GCC 11.

Any idea how that will interact with the non-GNU libcs (specifically musl and
uClibc)?

Try adding --enable-initfini-array to gcc config

Most likely GCC config is not detecting .init_array/.fini_array support which
is now always turned on the trunk for *linux-* targets.
