[Buildroot] How to change buildroot directory

[Marco Trapanese]

Hello,
I prepared a virtual machine with a fully configured (and compiled) 
buildroot filesystem/toolchain.
Now I have to transfer this buildroot environment to another machine, 
which has a different path of course.

How this could be done?

Currently I tried:

1) create from scratch a new buildroot clone on the new machine and use 
my .config. Disadvantages: you need to recompile everything and using 
the latest builds you cannot have the same version.

2) copy the whole buildroot directory: the problem is every Makefile has 
the old path... so it's not possible to launch a make without a full 
clean/make cycle.

What do you recommend?
Thanks
Marco

The host/build directory of buildroot is currently not relocatable, so
right now you only have option 1.

The issue is also listed in our TODO, but so far hasn't been
implemented:
