Also look at a 2018 message showing a short version of sleep compiled with nolibc:

$ echo "int main() { return sleep(3);}" | gcc -Os -nostdlib -include ../nolibc/nolibc.h -s -fno-exceptions -fno-asynchronous-unwind-tables -fno-unwind-tables -lgcc -o sleep -xc -
$ ls -l sleep
-rwxr-xr-x 1 willy users 664 Aug 23 20:37 sleep

At mine, for comparison, there's a 66-fold bloat:

ale@pcale:~/tmp$ ls -l `which sleep`
-rwxr-xr-x 1 root root 43808 Sep 24 2020 /bin/sleep
