/ Each of the following entries is needed to ensure that the
/ syscall.syscall_linux code can conditionally call these
/ function pointers:
/
/ 1. find the C-defined function start
/ 2. force the local byte alias to be mapped to that location
/ 3. map the Go pointer to the function to the syscall package
