Hopefully the list of supported platforms was outdated and aarch64 is still supported...

Musl isn't involved here. This looks to me to be a GCC bug, and this line
is the clue:

during RTL pass: reload
/mnt/agent/work/f25b6e4d8156543c/src/hotspot/share/runtime/synchronizer.cpp:1116:1: internal compiler error: in curr_insn_transform, at lra-constraints.c:3962
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.

I'd be interested to see the preprocessed C++.
