 This is a FAQ (well, actually, the reason we don't support it is because it
isn't asked very often...) [1].

It has been decided that support for the native compiler on the target would be
stopped from the Buildroot-2012.11 release because:

* this feature was neither maintained nor tested, and often broken;
* this feature was only available for Buildroot toolchains;
* Buildroot mostly targets small or very small target hardware with limited
resource onboard (CPU, ram, mass-storage), for which compiling on the target
does not make much sense;
* Buildroot aims at easing the cross-compilation, making native compilation on
the target unnecessary.

If you need a compiler on your target anyway, then Buildroot is not suitable for
your purpose. In such case, you need a real distribution and you should opt for
something like:

* openembedded
* yocto
* emdebian
* Fedora
* openSUSE ARM
* Arch Linux ARM
