There is a build issue with musl libc due to missing M_PI when _GNU_SOURCE is
not defined.

I suggest you add it in CFLAGS by using DIEHARDER_MAKE_OPTS:

DIEHARDER_MAKE_OPTS = CFLAGS="$(TARGET_CFLAGS) -D_GNU_SOURCE"

Don't forget to take into account Thomas's comment for the next version ;-)

Best regards,
Romain
