Which means that on this particular opsys (CentOS 5.6) I have to build
and install my own binutils, at least for recent GCC versions, since the
system binutils are at 2.17 and no newer precompiled version is
available. 

Thanks a lot

Well, the -mavx is added by -march=native. Thus, using -mno-avx might be 
enough - or you replace -march=native by something else. (However, in 
terms of performance, using AVX can make a diffence; thus, updating 
binutils cannot harm.)
