libdecnumber's configure.ac is for the host, not the target. As such, it
needs to remain in sync with gcc's. I'm pretty sure it's deliberate that
it still needs to select a format even with --disable-decimal-float.
The logic selecting for the target is in libgcc/configure.ac. That's the
only place disabling without <fenv.h> might make sense (and if an explicit
--enable-decimal-float={yes,bid,dpd} is given without <fenv.h>, give an
error). The only reason this really makes sense is that you can
legitimately have both glibc and uClibc multilibs, some with <fenv.h> and
some without, and libgcc's configure is run once for each multilib.
