sys/time.h no such file

Hi jergusg! 

First congratulations on the work! I saw that it worked well for others!

On linux mint 19.3, when I trying to run `make install` I take the following error:

`gcc k380_conf.c -o k380_conf
In file included from k380_conf.c: 23: 0:
/usr/include/linux/input.h:13:10: fatal error: sys/time.h: No such file or directory
#include <sys/time.h>`

What can I be doing wrong?

Tks!
