Really fix og9 "Fix hang when running oacc exec with CUDA 9.0 nvprof"
In my yesterday's commit 9ae129017c7fc1fa638d6beedd3802b515ca692b 'Fix og9 "Fix
hang when running oacc exec with CUDA 9.0 nvprof"', I wrongly blamed the og9
"Fix hang when running oacc exec with CUDA 9.0 nvprof" to be responsible for
the hang being back, when in fact it's only the later og9 "OpenACC Profiling
Interface (incomplete)" backport from trunk that introduced the problem.
The confusing thing was that the og9 "Fix hang when running oacc exec with CUDA
9.0 nvprof" commit appears *before* the og9 "OpenACC Profiling Interface
(incomplete)" backport that it relates to.
And, in addition to that, I pushed the wrong (incomplete) version of my fix.

maintainer-scripts: Speed up git clone in gcc_release
When doing the 8.4-rc1, I've noticed (probably also because of the dying
disk on sourceware) that git clone is extremely slow, and furthermore when
all of us have some local snapshots, it is a waste of resources to download
everything again. Especially for the -f runs when we'll need to wait until
git tag -s asks us for a gpg password interactively.
The following patch adds an option through which one can point the script
at a local gcc .git directory from which it can --dissociate --reference ...
during cloning to speed it up.
