Kubuntu 10.04, with gcc 4.4.3:

gcc -v
Using built-in specs.
Target: x86_64-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu 
4.4.3-4ubuntu5' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs 
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr 
--enable-shared --enable-multiarch --enable-linker-build-id 
--with-system-zlib --libexecdir=/usr/lib --without-included-gettext 
--enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.4 
--program-suffix=-4.4 --enable-nls --enable-clocale=gnu 
--enable-libstdcxx-debug --enable-plugin --enable-objc-gc 
--disable-werror --with-arch-32=i486 --with-tune=generic 
--enable-checking=release --build=x86_64-linux-gnu 
--host=x86_64-linux-gnu --target=x86_64-linux-gnu
Thread model: posix
gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)

My log.do_configure is here: http://pastebin.com/9ZPUB4KJ .  The error 
at the top is slightly concerning:

   1.
      configure.ac:32: error: Please use exactly Autoconf 2.64 instead
      of 2.65.
   2.
      config/override.m4:34: _GCC_AUTOCONF_VERSION_CHECK is expanded from...
   3.
      configure.ac:32: the top level
   4.
      autom4te:
      /media/d2/beagleboard/oebb/build/tmp-angstrom_2010_x/sysroots/x86_64-linux/usr/bin/m4
      failed with exit status: 1

But I'm not sure if that's the issue.
