From: Hechao Li <hechaol@fb.com>
[ Upstream commit 89cceaa939171fafa153d4bf637b39e396bbd785 ]
An error "implicit declaration of function 'reallocarray'" can be thrown with the following steps:
$ cd tools/testing/selftests/bpf $ make clean && make CC=<Path to GCC 4.8.5> $ make clean && make CC=<Path to GCC 7.x>
The cause is that the feature folder generated by GCC 4.8.5 is not removed, leaving feature-reallocarray being 1, which causes reallocarray not defined when re-compliing with GCC 7.x. This diff adds feature folder to EXTRA_CLEAN to avoid this problem.
v2: Rephrase the commit message.
