title: Adding multiple ARM toolchains to path
body: <p>So I am aiming to compile armv2 32 bit on my Mac such that it does not use the FP register which I have been told was not in earlier versions of arm 32 by my instructor.</p>
  
  <p>I am thinking that if I use an earlier version of the toolchain it might support armv2 so while I currently have gcc-arm-none-eabi-9-2019-q4-major added to path I might also add gcc-arm-none-eabi-8-2018-q4-major to path.</p>
  
  <p>Heres the issue both of them have the binary arm-none-eabi-gcc in them which is what I want to use and if I add both to my path... I am not sure how to specify whether to use 2019-q4 or 2018-q4's version of gcc. Any good ideas on how to set this up?</p>
  
  <p>Also as a bonus if anyone knows how to force compile as armv2 that would be useful too so I can see if earlier versions did not use fp. Thankyou!</p>
