kbuild: sparse needs CF not CHECKFLAGS
Documentation/sparse.txt tells to use:
make C=2 CHECKFLAGS="-D__CHECK_ENDIAN__"
However, this still doesn't enable endian checks. The correct syntax is:
make C=2 CF="-D__CHECK_ENDIAN__"
This documentation bug was introduced by the following commit:
commit 1c7bafe7206d928eaccbcbd08d868733e0fb7054

kbuild: clarify "make C=" build option
Clarify the use of "make C=" in the top-level Makefile, and fix a
typo in the Documentation file.

This `typo' was not a typo, as `CF' had been introduced much earlier, by:

[PATCH] kbuild: CF=<arguments> passes arguments to sparse
Allows to add to sparse arguments without mutilating makefiles - just
pass CF=<arguments> and they will be added to CHECKFLAGS.
