sandbox: support forcing 32-bit x86
If gcc supports multiple architectures, barebox uses only the default
when compiling for ARCH=sandbox, this is e.g. the case with compilers
that generate both 32- and 64-bit x86 executables.
There can be good reasons to force 32-bit though, e.g. to reduce memory
consumption while fuzzing or to temporarily avoid 32-to-64-bit warnings,
while running the static analyzer. Add an option for this.
