kbuild: remove cc-option-align
Documentation/kbuild/makefiles.txt says the change for align options
occurred at GCC 3.0, and Documentation/process/changes.rst says the
minimal supported GCC version is 3.2, so it should be safe to hard-code
-falign* options.
Fix the only user arch/x86/Makefile_32.cpu and remove cc-option-align.
