This makes LLVM tools (including dependent tools such as LLD) readily useful in
more situations, foresees such needed additions as BPF and NVPTX, and brings
llvm_6 and newer on par with the current default llvm_5.
This allows building Vala without support for Graphviz; useful for more
minimal installs where we don't want to pull it (and transitively,
pango, gd, etc.) in as a dependency.
- Require Coq 8.6.1+
- Split substituteInPlace call into patchPhase
- Constrain platforms correctly to x86_64 Linux/Darwin, which was all
it supported anyway (there was no way to properly configure i686 builds,
nor cross builds. In the future there might be)
- Minor stylistic cleanups
- Add new 'man' and 'doc' outputs (the previous attempt to move the
build artifact outputs into $lib no longer worked correctly and they
were installed into 'out' instead, this fixes it completely).
- Clean up weird binary artifacts left in $out (that were already
in $lib)
- Wrap ccomp to undefine _FORTIFY_SOURCE; otherwise it causes
annoying warnings on every invocation

This is to help QT find all the necessary plugin libraries at startup
time, otherwise it freaks out when run out of 'nix-env' environment or
run directly, e.g. `./result/bin/nextpnr-ice40 --gui`. The reason for
this is that none of the traditional paths it looks for are available.
The workarounds for this are to otherwise:
- Install e.g. into environment.systemPackages (presumably it will
then pick up QT libraries in /run/current-system/sw/lib/qt-*)
- Install 'qtbase' into your user environment (qt will also try to
load dependent libraries out of ~/.nix-profile/lib/qt-*)
However, this QT_PLUGIN_PATH wrapping hack is used elsewhere in the
tree, presumably to mitigate these (poor) workarounds, especially for
non-NixOS users. There seems to be no downside to this.
With this, I have been able to run NextPNR's GUI on an Ubuntu 16.04
system using the 'nixGL' hack by simply running the resulting binary
from anywhere (though there seems to be some glitching artifacts in the
floorplan UI, I suspect this is due to a buggy OpenGL stack rather than
any direct problem with NextPNR or the QT libraries themselves).
This does not mark the GUI build as non-broken yet, though. That will
happen in the future after a bit more testing and splitting nextpnr into
separate minimal/GUI attributes.
