+DD64 is from CFLAGS in the environment prior to configuration.

Broadly speaking, linking needs to be done with CFLAGS + LDFLAGS (not
just LDFLAGS) precisely because of flags like this. This is already how
Automake does things; the bug comes down to bash's build system not
following existing convention. It's not reasonable to have to duplicate
CFLAGS in LDFLAGS to avoid the reported link error.
