msym32 is not supported by LLVM toolchain. Workaround by probe toolchain support of msym32 for KBUILD_SYM32 feature.

Doesn't this reintroduce the failure fixed with commit a79a404e6c22 ("MIPS: Fix CONFIG_CPU_DADDI_WORKAROUNDS `modules_install' regression")?

If this call to `cc-option-yn' does need to be made here, then this whole stuff has to be wrapped into a `need-compiler' check, see the discussion: https://lore.kernel.org/r/alpine.DEB.2.21.2307180025120.62448@angie.orcam.me.uk/ and the other patches in the series.
