Source of this change goes back to 2009 and original version of
fetchgit at 205fb0c87e.
The nondeterminism is really caused by changing .git so leave other
files alone as they might be interesting.
Note: this causes a hash mismatch with Hydra's version of Git Plugin
which we should fix to comply.
Release announcement, 2016-01-30:
https://www.sigrok.org/blog/major-sigrok-releases-libsigrok-libsigrokdecode-sigrok-cli-pulseview
I first tried updating the projects in separate commits. But later I
found cyclic dependencies, that would break git bisect, so I ended up
squashing the commits:
* libsigrok: 0.3.0 -> 0.4.0
Enable building libsigrokcxx.so, the C++ bindings for libsigrok, by
adding doxygen, glibmm and python as build deps. This is needed for
Pulseview >= 0.3.0. Also update the firmware (sigrok-firmware-fx2lafw)
while at it.
* libsigrokdecode: 0.3.0 -> 0.4.0
* sigrok-cli: 0.5.0 -> 0.6.0
* pulseview: 0.2.0 -> 0.3.0
New dependency: glibmm (due to libsigrokcxx.pc from libsigrok).
Note that collectd is incompatible with the new libsigrok release, so
I let it use the old one (0.3.0).
This reverts commit 6ff886e539 because it
doesn't work when chroot builds are enabled (nix.useChroot = true):
$ nix-build -A arduino
these derivations will be built:

BUILD FAILED
Reasoning: without a revert, the build farm cannot produce binaries and
users that build from source, without chroot, cannot trust that they get
a working result (non-deterministic build, depending on how pure the
arduino builder is).
