David Gow ba6b328588 rust: arch: um: Fix building 32-bit UML with GCC 
32-bit UML builds can be configured either by setting CONFIG_64BIT=n or
with SUBARCH=i386. Both work with Rust-for-Linux when clang is the
compiler, but when SUBARCH=i386, we don't set a bindgen target correctly if
gcc is the compiler.

Add the appropriate bindgen target configuration for i386, as is done in
Makefile.clang.

[ For reference, the errors look like:

        BINDGEN rust/bindings/bindings_generated.rs
      error: unsupported option '-mno-sse' for target ''
      ...
      error: unknown target triple 'unknown'
      panicked at .../bindgen-0.72.1/ir/context.rs:562:15:
      libclang error; possible causes include:
      ...
