configure doesn't error out when --enable-dwarf-unwind is given but libdw cannot be found
Against expectations, the GHC bindist supposedly having DWARF support provided at
doesn't actually have DWARF support.
According to bgamari, this is because
./configure --enable-dwarf-unwind doesn't actually complain when the required dependency
libdw isn't found; instead, it continues silently.
Most programs I know will barf out when something isn't found but also *explicitly* requested via the command line; for the cases where this wasn't, the project maintainers did consider this a bug.
./configure suite should fail hard when
--enable-dwarf-unwind is given but
libdw cannot be found.
