Problem building 3.3.6 (with 3.4.4): xgcc: cannot specify -o with -c or -S and multiple compilations

[Andrew Walrond]

Thanks for replies. For the sake of closure, I can now report (after a *lot* 
of work isolating the problem) that this was due to sed crashing randomly and 
unexpectedly during the gcc build since a kernel upgrade from 2.6.11.12 to 
2.6.12.*

Go figure; gcc builds fine when running 2.6.11.12 kernel; sed (and sometimes 
other tools like rm) crashes randomly during build when running newer 
kernel... (same .config, vanilla untainted kernels)

I'm going to chase this down on LKML now. Sorry for the noise
