(When generating 64-bit code, ensure that any addresses used in 4 or 8
byte loads or stores of the form reg+imm have the lowest 2 bits of imm
set to zero, so that they can safely be used in ld/ldu/lda/std/stdu
instructions.)

distinction between primary and secondary build targets, and (2) make
it independent of the default behaviour of gcc (iow, what gcc does
when you specify neither -m32 nor -m64).
As a result, an out-of-the-box build on ppc64-linux now builds a
system which is basically for 64-bit PowerPC, but also has the ability
to run 32-bit ppc-linux binaries (exactly the same arrangement as you
get when building on amd64-linux).
There are various twists and turns. multiple-architectures.txt is
updated all the gory details.
This will break amd64 builds until such time as
<tool>/tests/{amd64,x86}/Makefile.am are fixed up (shortly).
