I think for Linux users is easier to have the modification in the Makefile.tpl
In my home folder, I have the following folder structure:
where the gcc-arm is a symlink to any of the gcc versions bellow, at my choice (or need).
So, inside the Makefile.tpl, the line looks like this:
BINPATH = $(HOME)/gcc-arm/bin�?

So, my Makefile.tpl template is a little more customized, because as many others, apart of the LL driver sources, in the PATH I want to include also my own folder with various libraries I use - this is how a part of my Project Explorer in Eclipse looks:
Where ll_library is a container of my libraries that are used by all the projects there.
Also, I need to specify in the CubeMX if I want to use printf with floating point support (in concordance with this post
https://community.st.com/0D50X00009XkW3aSAF
).So in the end, the template looks like this (maybe the developers will find some points valid)
