Summary:                    Unable to compile Buildroot
Description: 
Hi,

I'm running a virtual machine with Debian 32 bits installed (on a Xeon
core 2 server). I tried to install buildroot in x86_64 arch but I always
get the same error at last:

Unknown CPU given in --with-tune=core2.
make[1]: *** [configure-gcc] Error 1
make[1]: Leaving directory
`/usr/src/buildroot/toolchain_build_x86_64/gcc-4.2.1-initial'
make: ***
[/usr/src/buildroot/toolchain_build_x86_64/gcc-4.2.1-initial/.compiled]
Error 2

CPU is Intel Core2 2.13 GHz (according to cpuinfo)

Toolchain Config: 
- Toolchain type: Buildroot toolchain
- target arch x86_64
- variant arch core2
- kernel headers 2.6.24.x
- uClib = daily snapshot
- busybox 1.9.x
- gcc 4.2.1
- binutils 2.18
- multilib disabled

I reinstalled the official 64 bits Debian distrib, then updated the kernel
to 2.6.24.3 version. I changed sources list to testing repository to get
gcc 4.3: nothing new, I still have the same error message (Unknown CPU).

I solved the problem by specifying a Nocona CPU instead of a Core2 one.
Seems like  the Core2 does not support EM64T technology, unlike the Xeaon
Nocona. See http://softwarecommunity.intel.com/articles/eng/1699.htm
