Calin, All,

On 2018-03-25 13:18 +0300, Calin Crisan spake thusly:
> There are cases where a downloaded toolchain doesn't have its binaries
> placed directly in a "bin" subfolder (where BuildRoot currently looks
> for them).
> 
> A common example is the official Raspberry Pi Toolchain
> (https://github.com/raspberrypi/tools), which has its binaries in
> "arm-bcm2708/arm-linux-gnueabihf/bin".
> 
> This commit introduces BR2_TOOLCHAIN_EXTERNAL_REL_BIN_PATH that defaults
> to "bin" and can be changed as needed.
