Sage 5.0.beta10 fails to build using GCC 4.7.0 on Skynet/eno and other
Linux systems, for different reasons.
* GFan: #12760
* Givaro: #12761
* !LinBox: #12762
* !PolyBoRi: #12750, #12655
* MPIR on ia64 (Itanium): #12765 (GCC bug) -- #11616 also provides an
MPIR 2.'''4.0'''.p3 spkg working around this.
* MPFR on ia64 (Itanium): #12837 (same GCC bug) -- Note that MPFR is also
a prerequisite for building the GCC spkg.
* GMP-ECM, FLINT, NTL, PARI and zn_poly (as well as the Sage library) all
fail to build on ia64 due to the same bug,
* R fails to build on ia64 during byte-compiling; seems to be a different
issue, but same work-around works.
* Two files (`compat` and `linear`) of PARI's test suite fail due to
segfaults when compiling with `-O3`/`-O2`/`-O1`, at least on Linux x86_64.
* zlib on Solaris: #12800
* eclib on Solaris (see comments below; this is a Solaris header issue,
will be fixed in a new spkg at #10993)

pulled in, which isn't present on other systems.
Now fixed in the new upstream tarball (eclib-2012-04-15.tar.gz), by
renaming the function. (See #10993.)
