It requires kernel 4.4+ compiled with certain kernel options. This patch checks if kcov header "sys/kcov.h" is present on build machine, and stores the result in variable CONFIG_KCOV, meant to be used in linux-user code related to the support for three ioctls that were introduced at the same time as the mentioned header (their definition was a part of the first version of that header).
