Currently the x86_64 version of valgrind is not able to run 32bits applications due to a --enable-only64bit flag used when running ./configure script during valgrind building process. I'm not sure what was the motivation to disable this functionality but it would be good to be able to run 32bits apps as well. Is it possible to enable this feature?

Additional info:
* package version: 3.9.0-1

Steps to reproduce:
$ echo "int main(int, char**) {}" | g++ -m32 -x c++ - && valgrind ./a.out
valgrind: failed to start tool 'memcheck' for platform 'x86-linux': No such file or directory
This task depends upon

There would need to be a valgrind-multilib added to the [multilib] repo where the multilib toolchain resides as our [core] and [extra] repos are pure 64 bit.
