I just had a look at glibc-20040830, and it's still needed and useful
for this version.  glibc-20040830 out-of-the-box still contains the
following wrong assumptions:
- sysdeps/arm/bits/endian.h: float word order is big endian (which it is
  not on vfp systems)
- sysdeps/arm/gmp-mparam.h: IEEE doubles are mixed endian (which they
  are not on big endian systems, neither on vfp systems)
- sysdeps/arm/ieee754.h: IEEE doubles are in little endian byte order
  (which they are not on big endian systems)

glibc-vfp.patch from crosstool 0.28rc36 seems the right solution for
all of these issues.
