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
   https://lwn.net/ml/linux-kernel/20180823190657.GA12057%401wt.eu/

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


Best
Ale
