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@qemux86-64:~# gcc -m64 t.c -o t root@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@qemux86-64:~# ./t Hello World ! root@qemux86-64:~# gcc -m32 t.c -o t root@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@qemux86-64:~# ./t Hello World !
