execl(3) is a libc function. It and its cohorts may be found in
the directory "lib/libc/gen". execve(2) is the system call, which
does the dirty work, so the generated "source" is just a stub which
invokes the syscall mechanism. The actual function, which is invoked
in the kernel's context, is sys_execve() in "sys/kern/kern_exec.c".
