libexec/ld.so : Makefile loader.c syscall.h
Log message:
Lookup the start,len of the "execve" stub in libc.so, and tell the kernel
where it is with pinsyscall(). In non-static binaries, kernel execve(2)
will now insist upon being called from that small region. Arriving from
a different region smells like ROP methodology, and the process is killed.
