Linux build linux-armel is failing

[tresf]

Running ./build-hidapi.sh linux-armel results in an error.

• When running this build an error occurs stating that claims a header is missing.

  hid.c:44:10: fatal error: libudev.h: No such file or directory
  44 | #include <libudev.h>
     |          ^~~~~~~~~~~
  

Furthemore, the toolchain seems to be wrong:

• The toolchain seems to be incorrectly using the hf suffix
  • gcc-arm-linux-gnueabihf should be gcc-arm-linux-gnueabi
  • --host=arm-linux-gnueabihf should be --host=arm-linux-gnueabi
  • libudev-dev:armhf should be libudev-dev:armel

I attempted to fix this by hand, but after a few unsuccessful builds dockcross is telling me You don't have enough free space in /var/cache/apt/archives/., which I can't figure out how to fix. 😆
