[PATCH] Makefile: fix config cc version check

.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.
