Description

Linux commit v5.16-rc3-26-g129ab0d2d9f3

Added quotes around "$(CONFIG_CC_VERSION_TEXT)", however
.config stores CONFIG_CC_VERSION_TEXT with quotes thus
breaking the GNU make Makefile for external modules.

We need to supply a non-quoted value and override the
value in .config before it is used.
