Remove a build-time check for the presence of the GCC `-msym32' option.
This option has been there since GCC 4.1.0, which is below the minimum
required as at commit 805b2e1d427a ("kbuild: include Makefile.compiler
only when compiler is needed"), when an error message:

arch/mips/Makefile:306: *** CONFIG_CPU_DADDI_WORKAROUNDS unsupported without -msym32. Stop.

started to trigger for the `modules_install' target with configurations
such as `decstation_64_defconfig' that set CONFIG_CPU_DADDI_WORKAROUNDS,
because said commit has made `cc-option-yn' an undefined function for
non-build targets.
