Xen users - Nov 2012 - How to set GCC version for ovmf compilation

Hi all

I''m trying to compile xen tools with OVMF firmware, but the compilation
fails due to the hardcoded use of gcc44 for OVMF.
If I download the EDK2 source I get the same error if I set gcc to 4.4 but
actually have 4.7, however, a patch is available for gcc47.
I have tried to install both gcc46 and get the same error. I also tried gcc44 by
instead get a python error.

Gcc46 and gcc47 error when running make dist-tools

I am using a Ubuntu guantal with recompiled binutils to include all targets. But
is should not have any effect. The problem is that I cannot set the gcc version
for OVMF to say 4.6 which should do the job fine.

Hope someone has a workaround. However, it might be best to make the BaseTools
for EDK2 (OVMF) on in the make routine instead of relying on a precompiled set.
