[Buildroot] external-toolchain with CodeSourcery works well

[Charles Krinke]

I was able to take buildroot-2011.02 and select the CodeSourcery
external-toolchain. The CodeSourcery 2010.09.tar.bz2 downloaded and
installed in buildroot-2011.02/output/external-toolchain and created jffs2,
ubifs, cpio and tar root filesystems along with an external application with
a path to the same toolchain. Great job getting this part working in
buildroot.

I do see a powerpc-linux-gnu-gdb and gdbserver, both of which run. The
gdbserver runs on the PowerPC target and does make a connect.

Toolchain is gcc-4.5.1 and it looks like the notion of "target remote
targetIp:port" has now become "target extended-remote targetIp:port". When
the remote debugger disconnects, the target now goes back to waiting for a
connection which is a bit better then previous versions.

Now, I am going to attempt to understand a bit about crosstools-ng. Here, I
am guessing a bit on configuration settings, that is, things like prefixes
and paths. Any suggestions would be gratefully appreciated.
