been a long time since I tried this as well, but I believe you want to
check out gcc last,
and IIRC something to the effect of the following can work for
checking out into a combined working directory (not really tested)

GIT_DIR=~/git/binutils-gdb/.git git read-tree  master
GIT_DIR=~/git/binutils-gdb/.git git checkout-index -u -f -a

GIT_DIR=~/git/gcc/.git git read-tree  master
GIT_DIR=~/git/gcc/.git git checkout-index -u -f -a
