.config is of the form: CONFIG_CC_VERSION_TEXT="gcc (GCC) 11.2.1 20220127 (Red Hat 11.2.1-9)" while CC_VERSION_TEXT is of the form: gcc (GCC) 11.2.1 20220127 (Red Hat 11.2.1-7) thus when comparing these, CONFIG_CC_VERSION_TEXT should not be put in "", otherwise we get () outside "" which shell then tries to evaluate.
