Hide GCC configuration

Development

Hi guys ,

Hiding GCC can allow for greater security when the kernel is studied by an attacker,
while also being protected from forensic analysis.

Modification kernel/init/Kconfig

# hide the GCC version
config CC_VERSION_TEXT
	string
	default "1111111111111111111" 
------
config GCC_VERSION
	int
	default "1111111111111111111" if CC_IS_GCC
	default 0
------ -- ---
# hide identification
config AS_IS_GNU
	def_bool $(success,test "$(as-name)" = 11111)

config AS_IS_LLVM
	def_bool $(success,test "$(as-name)" = 11111)
--------------
# hide forensic identification
config AS_VERSION
         int
	# Use clang version if this is the integrated assembler
	default CLANG_VERSION if AS_IS_LLVM
	default "1111111111111111111"

config LD_VERSION
	int
	default "1111111111111111111" if LD_IS_BFD
	default 0
-------------------------

Example .
CONFIG_AS_VERSION=23800
This allows the proximity of a kernel version 5.15.x 5.16.x Kernel
This allows for forensic analysis.

The kernel build is correct.
it is better to hide as much information from the kernel that can be used
