New description:
The error is exactly the same as the one reported for MPIR at #12765
("impossible reload").
The spkg below also fixes some other issues, and applies all official
upstream patches published so far.

=== mpfr-3.1.0.p1 (Leif Leonhardy, April 13th 2012) ===
* #12837: Work around GCC 4.7.0 bug on ia64 (Itanium), unfortunately by
almost
completely disabling optimization on that platform. (MPFR is also a
pre-
requisite for building the GCC spkg; after that has been built, MPFR
will
get rebuilt with normal optimization.)
* Use `patch` to apply patches.
* Apply all recent "official" upstream patches; the resulting MPFR
version
then is 3.1.0-p8.
* Properly quote the parameter to the `configure` option `--libdir`.
* Export `CFLAGS`! Previously MPFR would not even have used "its own"
flags
(extracted from `config.status` after configuring it with `CC` and
`CFLAGS`
unset) if `CFLAGS`, set in its `spkg-install`, weren't already
exported.
(Also export `CPPFLAGS` and `LDFLAGS`, to which `$CFLAG64` is now also
added
if `SAGE64` is `yes`.)
* Add `$CFLAG64` to *required* `CFLAGS` if `SAGE64=yes`.
* Clean up the spkg; redirect all warnings and error messages to stderr;
add
some messages.

Comment:
Ok, now committed the changes, new spkg is at the same, usual place.
It uses `required_cflags` for `$CFLAG64`; the rest is still in.
