I agree, this is a bit odd.

@Edward: Is this correct as it currently is? Would be great if this changeset
could finally get merged as Debian just recently bootstrapped riscv64 and
is now building packages on real hardware with 10 build machines running:

I assume the build dependencies for OpenJDK in Debian will be built in around
a week or so. Until I then, we should have sorted this patch out so I can
add a (backported) patch to Debian's openjdk-8/9/10/11 packages.
