Commit f57ba2d30c ("cmake: toolchain_cc_imacros: don't use space
separated arguments") moved toolchain_cc_imacros() to using the long
argument format in order to avoid spaces that CMake uses to delimitate
and deduplicate arguments.
It seems that xcc doesn't support the --imacros=foo form. However
it does support the short "combined" -imacrosfoo form (without space).
So let's use that instead and document the caviat.
