gcc 5 is in experimental, so I guess it should be the experimental
chroot but with forced gcc 4:5
there are various ways I guess to achieve it, but here is a fully
scripted one ;)
mkdir -p /tmp/exp-hooks; echo -ne '#!/bin/sh\nget install -t experimental gcc g++\n' >| /tmp/exp-hooks/E0expgcc; chmod +x /tmp/exp-hooks/E0expgcc
sudo pbuilder --create --mirror http://http.debian.net/debian --distribution experimental --hookdir /tmp/exp-hooks
NB might want to dump it to some other than base.tgz file

FWIW -- some of them seems to be due to internal problems with gcc
package(s) as far as I see it, e.g. in scipy
gfortran:f77: scipy/fftpack/src/dfftpack/zffti.f

so it might be first worthwhile clarifying with Matthias:
- aren't those really just have to do with internal gcc package issue
and mass bug filing was a bit undue?
- is there a page summarizing gcc 5 issue so they could be efficiently
tackled?
