Now CONFIG_{GCC,CLANG}_VERSION are always 6-digit, replace the shell
invocations with the test-ge macro.
Please note gcc-min-version must be used against a 6-digit number.
Add '0' prefix.

gcc-min-version
gcc-min-version tests if the value of $(CONFIG_GCC_VERSION) is greater than

Example::
- cflags-$(call gcc-min-version, 70100) := -foo

In this example, cflags-y will be assigned the value -foo if $(CC) is gcc and
