x86, lto: Enable Clang LTO for 32-bit as well
Commit b33fff07e3e3 ("x86, build: allow LTO to be selected") enabled
support for LTO for x86_64 but 32-bit works fine as well.
I tested the following config combinations:
* i386_defconfig + CONFIG_LTO_CLANG_FULL=y
* i386_defconfig + CONFIG_LTO_CLANG_THIN=y
* ARCH=i386 allmodconfig + CONFIG_LTO_CLANG_THIN=y
with LLVM 11.1.0, 12.0.0, and 13.0.0 from git without any build
failures. The defconfigs boot in QEMU with no new warnings.
