The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
It was really ugly that `xlibs.xlibs` meant something else than `xlibs`,
especially when using `with xlibs`, such as in wine.
Also, now `xlibs` is the same as `xorg`.
vimdot doesn't work at the moment because one of its dependencies,
'which', is missing; vimdot fails to find gvim or vim and aborts.
Instead of adding a dependency on 'which', replace it with the POSIX
command 'command -v'.
The cdt.h header duplicates the signatures of standard library functions
memcmp() and strcpy(), but those signatures don't match the real thing when
building with a C++ compiler, because they lack the no-throw declaration glibc
has. Simply dropping those redundant prototypes remedies the issue.

* New function makeFontsConf to generate a fontconfig configuration
file. Moved from NixOS.
* dot2pdf: use makeFontsConf to generate a fonts.conf containing just
the Ghostscript fonts (see NIXPKGS-29).
* dot2pdf: generate PDF directly, don't go through PS. Note that this
and using fontconfig changes the interpretation of "fontname"
attributes in dot graphs.

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
