The error message is not "you failed, try some random other thing". It 
explicitly tells you that it tried to find a program called m4 (which is 
necessary for the build) and couldn't find it. So you need to install that 
before you can build GMP.

Plugging this exact error message in a search engine leads to 
https://stackoverflow.com/q/7902894/1918193 and many others.

Note that since this is Ubuntu, it would be easier to install pre-built 
packages with

sudo apt install libgmp-dev
