Kbuild compiles all the $(obj-y) files. It then calls

In the above example, -Wno-unused-but-set-variable will be added to

- cc-version
- cc-version returns a numerical version of the $(CC) compiler version.
- The format is <major><minor> where both are two digits. So for example
- gcc 3.41 would return 0341.
- cc-version is useful when a specific $(CC) version is faulty in one
- area, for example -mregparm=3 was broken in some gcc versions
- even though the option was accepted by gcc.
-
- Example:
- #arch/x86/Makefile
- cflags-y += $(shell \
- if [ $(cc-version) -ge 0300 ] ; then \
- echo "-mregparm=3"; fi ;)
-
- In the above example, -mregparm=3 is only used for gcc version greater
- than or equal to gcc 3.0.

cc-ifversion
cc-ifversion tests the version of $(CC) and equals the fourth parameter
if version expression is true, or the fifth (if given) if the version
