When you discussed the situation requiring the startfiles revert patch 
with upstream they reviewed DIY's build process. Their answer, several 
times, was 'use sysroot': http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35532

There might seem to be, but it's not really. The only new stuff is 
really the sysroot bit. The other changes in pass 1 gcc are really just 
things we were already doing in pass 2 and in the adjusting toolchain 
section to prevent hard-coded searching through /usr
