The problem is likely a recursive make call "$(MAKE)" in combination with parallel execution. As far as I understand it, GNU make cannot track dependencies properly, which can lead to partial or invalid dependency graphs. One make process can modify a file while another uses the file. The permission error or ETXTBSY error are manifestation of one process creating an executable while another process is attempting to execve() it. The paper https://accu.org/journals/overload/14/71/miller_2004/ explains the issues with recursion in great detail.
