gcc: enable multilib for target gcc

- add a task to setup multilib configuration for target gcc
- this commit adapts Nitin Kamble's work to gcc 4.7
- use a hash for storing arch-dependent multilib options
- patch gcc in order to use the multilib config files from the
build directory

Tests:
root at qemux86-64:~# gcc -m64 t.c -o t
root at qemux86-64:~# file t
t: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped
root at qemux86-64:~# ./t
Hello World !
root at qemux86-64:~# gcc -m32 t.c -o t
root at qemux86-64:~# file t
t: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped
root at qemux86-64:~# ./t
Hello World !
