[Buildroot] Using Buildroot generated toolchain on different machine without Buildroot environment

[Aleksandar Zivkovic <Aleksandar.Zivkovic@rt-rk.com>]

Hi all,

I'm trying to extract the toolchain generated by Buildroot in order to 
use it on other machines without Buildroot environment. Thought this is 
simple and did the following way:
* generate toolchain outside Buildroot (BR2_HOST_DIR="$(TOPDIR)/../host")
* use files from $(TOPDIR)/../host on other machine

To test my procedure I modified toolchainfile.cmake file with paths on 
other machine and started cmake -DCMAKE_TOOLCHAIN_FILE="..." .
Unfortunately this doesn't work :( cmake is not able to generate 
makefiles complaining on the following:
i686-linux-gcc: error trying to exec 'cc1': execvp: No such file or
   directory

Google shows posts on this problem but I have a feeling that I missed 
the idea on how to isolate toolchain for usage on other machines so 
would like to ask help from you.

Thank you in advance,
Aleksandar
