Some of the patch adds ARM support, and this is done in the most
minimal way possible.  Some of it is a backport from upstream, and
some of it is a bug that I'm discussing with John Rose who wrote
hsdis.  This hunk simply makes sure that hsdis itself is built withe
debugging enabled.

None of this can possibly affect any IcedTea release, because hsdis is
never built as part of an IcedTea build on any architecture.  It's
purely provided as a utility for people debugging IcedTea.
