New description:
MPIR builds libraries that have the "executable stack" flag. This breaks
in Fedora 14 which tightened SELinux rules to disallow executable stack
libraries by default.
Note that the MPIR libraries do not need executable stack permissions, the
flag is set erroneously. Probably because gcc can't figure it out
automatically for assembler code.
Updated spkg is here:
http://www.stp.dias.ie/~vbraun/Sage/spkg/mpir-1.2.2.p2.spkg
The only change was that the spkg-install tested whether the `execstack`
utility is installed and then used it to clear the flag after the make
step.
The new spkg now simply adds `-Wl,-z,noexecstack` to `LDFLAGS` on Linux.

Comment:
Although both the commit message and the changelog entry lack a back-
reference to this ticket, positive review.
I think we can safely (and should) merge this into 4.6.1, since
unfortunately the MPIR upgrade (#8664) is again delayed by trouble with
the necessary GMP-ECM upgrade (#5847) for a couple of reasons (mainly
weird MacOS X PPC issues).
