[poky] External Toolchain

[Anjandeep Sahni]

Hi all,

I am fairly new to poky. Just had a few queries.

I wanted to know where exactly in the build directory does poky build 
the default toolchain.
And also if I have to use an external linaro toolchain, how would I go 
about it? Should I just include the meta-linaro layer, and add the 
TCMODE variable to local.conf?
I downloaded and extracted the prebuilt binaries for linaro toolchain. 
How do I point my build system to use these instead of the default 
toolchain?
