Urr, that's standard GNU boilerplate guff.  I don't know if it applies
to us or not.

Anyway (unless I misunderstand something) this should work right out
of the box, no monkey business, no nothing.

   ./configure --prefix=/place/i/want/it/installed
   make
   make install

Then /place/i/want/it/installed/bin/valgrind should be able to handle
both 32-bit and 64-bit executables.  One thing to look out for, though,
is at the end of the ./configure run: you need to see

       Primary build target: AMD64_LINUX
     Secondary build target: X86_LINUX

If you don't get that, then you will indeed be out of luck (w.r.t. a 
dual-arch build.)
