[Suggestion] arch: avr32: compiler: compiling tools issue

[Chen Gang]

Hello Maintainers:

With allmodconfig, and set "avr32-linux-gnu-" as cross compiler prefix.

It will report error:
  avr32-linux-gnu-gcc: error: unrecognized command line option ‘-mno-pic’
  avr32-linux-gnu-gcc: error: unrecognized command line option ‘-march=ap’

The related gcc version:
  [root@dhcp122 linux-next]# rpm -qf /usr/bin/avr32-linux-gnu-gcc
  gcc-avr32-linux-gnu-4.7.1-0.1.20120606.fc17.x86_64

Can we say: it is compiler's issue, and I need try to compile the cross
compiler to test it again ?

Welcome any additional suggestion or completions.

Thanks.

Interesting version, 4.7.1.

I would assume so, I didn't know Atmel finally pushed all the source code to
support avr32-linux from upstream.

I still use a jay old 4.2 based GCC port, which was the last one I used when
working for Atmel.

Is it possible to use the compiler tools (may from source code and
compile the compiler tools firstly), to compile the latest upstream
kernel (e.g next-20130624) for avr32 ?

Thanks.
