87a0201107 ppc64-linux: apply the bogus-LR kludge in a second place.

4936ed62d7 Deal with somewhat dubious numbers showing up from the kernel for the 
r3 (syscall return) value in the ucontext for a signal interrupting a
syscall.

a9bbc3690b Fix an all-platforms bug introduced by the recent overhaul of function 
interception and wrapping.  This was causing failures matching
function names in suppressions to function names in backtraces when
the latter names were Z-encoded (eg malloc), which typically caused
all leak suppressions to fail because they contain names such as
malloc, which are Z-encoded.

accordingly.

032abb3cdf Rewrite VG_(translate) to make it clearer (it had grown like Topsy for 
a long time) and to use the new preable-generating callback facility
supported by Vex.  Use this to add support for R2 saving/restoring

e626b54566 Tidy up ELF symbol table reading a bit. Make a completely new 
function for reading ELF symbol tables on ppc64-linux so as to avoid
cluttering up the {x86,amd64,ppc32}-linux cases with convoluted
hoop-jumping needed to handle both the dotful (older) and dotless
(newer) ppc64-linux ABI variants.

which it isn't when it is allocated as a static variable in the data

32f134b8c1 Somewhat rehash the biarch-build machinery so as to (1) formalise the 
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).
