# fails currently on final linking even with modified snmalloc build script to
# find static version of libatomic and libstdc++. With clang as the c++ compiler,
# this works, but to keep this image simple, we don't use it for now.
#
# TODO check with snmalloc-rs folks to see if there's a way around the snmalloc
# linking issues seen here.
