powerpc: make iSeries boot again
On ARCH=ppc64 we were getting htab_hash_mask recalculated
to the correct value for our particular machine by accident.
In the merge tree, that code was commented out, so htab_hash_mask
was being corrupted.
We now set ppc64_pft_size instead which gets htab_has_mask
calculated correctly for us later. We should put an
ibm,pft-size property in the device tree at some point.
Also set -mno-minimal-toc in some makefiles.
Allow iSeries to configure PROC_DEVICETREE.
