This fixes the previous attempt (in commit 46d1dd5) to make ctags' ctags
override emacs' ctags. The higher the value of the priority attribute,
the higher the priority (see the definition of `buildEnv`).
Multitarget option builds gdb with support for all targets. That's
similar to gdb-multiarch package in Ubuntu or gdb with multitarget
USE-flag in Gentoo.
This will probably be mandatory soon, and is a step in the right
direction. Removes the deprecated meta.version, and move some meta
sections to the end of the file where I should have put them in
the first place.
Regression introduced by df2b9b48cb.
This breaks the build for ltrace and other programs using libelf,
because the header file relies on features from glibc >= 2.22.
Here is an excerpt from the log output of the configure script from
ltrace:
In file included from ...elfutils-0.165/include/gelf.h:32:0,
from conftest.c:57:

The issue has been reported in the Debian bug tracker at
https://bugs.debian.org/810885 and I'm using the patch from Mark
Wielaard that has been posted there which adds compatibility for older
glibc versions.

Also, install programs with the "eu-" prefix to prevent collisions
with binutils (as recommended by upstream), enable xz support, and
enable deterministic archives.

The mass errors on Hydra seem transient; I verified ghc on i686-linux.
Only darwin jobs are queued ATM. There's a libpng security update
included in this merge, so I don't want to wait too long.
This patch fixes compilation errors when using ccache wrapper:
```
cc1: error: /nix/store/19vvbsjs6l6j0r22albzhysxfvr94imf-ccache-links/lib/gcc/*/*/include-fixed: No such file or directory
```
