[Buildroot] Problem building buildroot SVN under ia64

[Francois Visconte <fv@kh3.org>]

Hello,

I'm trying to compile buildroot SVN (from today) from amd64 to ia64
(itanium2).
The problem occures when compiling the gcc cross compiler (same error on
gcc 3.4/4.1.2/4.2.0)
The problem seems to come from
"toolchain_build_ia64/gcc-4.2.0/gcc/config.gcc" where
the variable "supported_defaults"  is not set for ia64. The result is
the following error during gcc compile:
