Build issue with Advance Toolchain

Hi,

I'm trying to compile psycpg2 on Power. For full optimization, I use Advance
Toolchain (AT), which is an extended version of GCC for Power.

The problem is: Parts of the code honors CC variable, part of does not.

Here is what I'm getting (see the difference between lines 1&2 and 3)

Can you please let me know how I can fix this?

Thanks!
