I stole your diff yesterday, when I built a static snapshot for fun.
> The plan is to use lld (the llvm linker) on arm64 to avoid GLPv3

> and ldapctl.

> The problem here is that the code uses the SHA1 functions in
> libcrypto, but doesn't explicitly link against that library. With our
> ancient binutils we don't notice this, because we link against libtls,
> which as a DT_NEEDED entry for libcrypto. But lld doesn't fall for
> this. And I believe modern binutils don't do this either.
