In 4.1, the build system changed, and it now wants to execute ld like this:
ld -r -o util/scripting-engines/libperf-in.o util/scripting-engines/trace-event-perl.o util/scripting-engines/trace-event-python.o
The actual problem seems to be that `buildInputs = [elfutils ...]`
causes 'ld' to point to elfutils in PATH instead of the usual binutils.
So remove elfutils from buildInputs and set NIX_CFLAGS_* manually. This
is a slight hack, but there is some precedent:
0761f81da7/pkgs/tools/package-management/rpm/default.nix (L13)Fixes#9095.
Or else users may see this unfriendly message:
error: cannot coerce null to a string, at .../nixos/modules/services/x11/display-managers/gdm.nix:107:49
Second attempt to resolve this issue. Copies stage1 image into expected
place manually. This has been improved in rkt master where there is a
configure option for specifying the location of this file. Can update
when next stable rkt is released.
Local build and run successful.
From the ChangeLog:
```
Version 0.7.77, 2015-09-02
+ #B941, MXF: files having only a video stream and an ancillary data
stream were having incorrect second video stream
+ MOV: detection of r210 CodecID as raw RGB

first one was detected)
x MPEG-TS: Wrong demux of TSP (188+16 TS) files having PES with only

x #B947, Amazon S3 support (REST API v2), CLI/DLL only and if compiled

```
The v0.8 build was broken because the CTAN package updated to v0.9 and
CTAN doesn't keep old versions of packages.
Besides bumping the version, this commit changes the src url from the
unversioned CTAN link (which would break the derivation every time a new
version of the package released, as it did yesterday) to the versioned
Github release link.
