That's not what actually happens.  CCFLAGS and CCFLAGS_FOR_BUILD share a
common set of options but differ in their use of CPPFLAGS and CFLAGS.  The
link is done with LDFLAGS_FOR_BUILD.  It's hard to tell where the DD64 is
coming from, since it doesn't get added by anything in the bash configure
scripts, but I suspect it gets put into LOCAL_DEFS somehow.
