I'm writing this as a bug for the GMP community and CCing coreboot,
although, with the proper direction I can imagine this all ending in a
change to the configure flags in the coreboot xgcc build.
The coreboot project contains a build script for generating a cross
toolchain (xgcc). The versions were recently bumped to:
GMP_VERSION=5.0.5
MPFR_VERSION=3.1.0
MPC_VERSION=0.9
LIBELF_VERSION=0.8.13
GCC_VERSION=4.6.3
GCC_AUTOCONF_VERSION=2.64
BINUTILS_VERSION=2.22
For the purposes of this bug, the important change was the move from GMP
5.0.2 to GMP 5.0.5. The issue is that an xgcc toolchain built on one
host cannot consistently be moved to a similar operating system on a
different host with a different underlying architecture. This was seen
with both 32bit and 64bit OS installs under the following configurations:
64bit Build Host

The following issue symptom does not seem to be limited to Linux
operating systems. Cygwin builds using Windows XP VMs and native
Windows installs also exhibit the problem. On Linux systems, in the
coreboot build on the execution host using a tar'd and copied binary
toolchain from the build host resulted in messages like:
libpci/libpci.c:221:1: internal compiler error: Illegal instruction

<snip>
On Cygwin systems, the build resulted in messages like:

I performed a bisect of the GMP mercurial repository and identified an
offending changeset:
http://gmplib.org:8000/gmp-5.0/rev/2b7b8ada8a20
By this, I mean, that the xgcc toolchain, when built with any change
prior to this GMP version, was able to compile coreboot when moved
between build and execution host. I constructed a patch for GMP 5.0.5
reversing this change (attached). Similarly, with this patch, the xgcc
toolchain using GMP 5.0.5 is portable.
Are the tuning changes made in this change optimal? What are the GMP
recommendations for constructing a toolchain that is portable between
similar hosts?
Thanks,
Ray

Patch for GMP 5.0.5 to reverse change that broke portability between two 64 bit machines with different chipset or two 32bit machines with different chipset.
The original changeset is in the GMP mercurial repository:
http://gmplib.org:8000/gmp-5.0/rev/2b7b8ada8a20
This issue is tracked internally by Sage Electronic Engineering under BugID: 1881
