[Pkg-openmpi-maintainers] Bug#579505: openmpi should use the atomic builtins provided by GCC

[Matthias Klose]

Package: openmpi
Version: 1.4.1-3

config/ompi_config_asm.m4 just checks a set of known architectures for atomic 
ops and errors out in other cases with "No atomic primitives available for 
$host".  See "Built-in functions for atomic memory access" in the gcc manual. 
The package should build on armel as well.
