[Buildroot] [pull request] Pull request for branch remove-external-toolchain

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

This patchset removes the external source toolchain feature from
Buildroot. It was used to build AVR32 toolchains because the AVR32
architecture is unfortunately not supported by upstream
gcc/binutils/gdb/uClibc. So the whole external source toolchain
infrastructure was implemented to allow to get these components from
other places than the normal mirrors.

However, this infrastructure is far more complicated than it needs to
be. This patchset replaces it by integrated the avr32 special versions
as normal gcc/binutils/gdb/uClibc versions. The respective .mk files
detect whether the version name contains avr32, and if it does, then
it switches to the AT91 mirror. Only the latest versions of
binutils/gcc/uClibc/gdb for AVR32 were kept (they are already fairly
ancient).

I've compiled tested an AVR32 toolchain + BusyBox and an ARM toolchain
+ Busybox.
