This bug is showing in the petsc build logs.

The previous version of petsc built successfully on mips but not
mipsel.  At that time the version of openmpi on mips was 1.10.2-5 (it's
now 1.10.2-11).  That suggests the bug is in the patches for 1.10.2-6
or later.

The petsc build failure on mipsel started under openmpi versions
1.10.2-5 and 1.10.2-7, but with a different (unresolved) error, not the
segmentation fault.  The mpicc segfault (more precisely for petsc, the
failure in FortranMPICheck) first appears on mipsel using
openmpi 1.10.2-9.
