This has surfaced since d990aa7163.
The "simpleUefiGummiboot" installer test fails since this commit,
because that commit introduced a small check to verify whether the store
was altered.
While installing NixOS for the first time, the store is usually in
/mnt/nix/store and without the read-only bind mount that's preventing
programs from altering the store.
So after nixos-install is done creating the system closure and setting
it as the active system profile, the bootloader is written from the
closure inside the chroot. The systemd-boot-builder is invoked during
this step, which adds .pyc files for various Python modules of the
Python 3 store path, which in turn invalidates the hash of the Python 3
store path itself.
At the time the system is booted up again, the nix-store is verified and
fails with something like this:
path /nix/store/zvm545rqc4d97caqq9h7344bnd06jhzb-python3-3.5.3 was
modified! expected hash
b2c975f4b8d197443fbb09690fb3f6545e165dd44c9309d7d6df2fce0579ebeb, got

Running the interpreter with the -B argument prevents Python from
writing those byte code files:

This basically does something similar than the AUR build:
https://aur.archlinux.org/packages/vlc-qt5/
On our side, all there is to do is to force compiling using C++11 mode
and use a patch that the AUR package took from the following upstream
patchwork URL:
https://patches.videolan.org/patch/14061/
Instead of passing CXXFLAGS to the configure script, I'm using sed here
to make sure we don't override flags figured out by configure.
For example if ./configure is used with CXXFLAGS=-std=c++11 appended or
prepended, we have something like:
... -I../include -std=c++11 -Wall -Wextra -Wsign-compare ...
While if we don't do that at all, we have something like:
... -I../include -g -O2 -Wall -Wextra -Wsign-compare ...
Another way would be to use NIX_CFLAGS_COMPILE, but that would affect
even compilation of C code and thus resulting in a bunch of warnings
like this:
cc1: warning: command line option '-std=c++11' is valid for C++/ObjC++
but not for C
So with our approach the flags during build look much better:
... -I../include -std=c++11 -g -O2 -Wall -Wextra -Wsign-compare ...
Another thing I've changed is that the vlc_qt5 attribute in
all-packages.nix now uses the latest Qt 5 version, because the build for
Qt >= 5.7.0 is now no longer broken.
I've also ordered the preConfigure attribute before the configureFlags
attribute, because it makes more sense in terms of context (pre ->
configure -> post).
Tested by building on x86_64-linux with libsForQt56.vlc, libsForQt58.vlc
and vlc (the Qt 4 version, just to be sure I didn't accidentally break
it).
