It's to separate from other changes coming from master.

We already have backward compatibility symlinks for ncurses libraries
and pkg-config files (when built in unicode/wide mode). The last bit is
to add a symlink from ncurses5-config to ncursesw5-config, which is what
this commit does.
To make e.g. "pkg-config --cflags ncursesw" work.
The ncurses expression, when built in unicode/wide char mode, provides
backward compatibility symlinks from lib<name>.so to lib<name>w.so.
Provide similar symlinks for the *.pc files: <name>.pc -> <name>w.pc.
The testsuite can fail under high load:
check_check_master.c:356:F:Core Tests:test_check_all_msgs:99: Expected Passed, got Test timeout expired
http://hydra.nixos.org/build/7243912
Sometimes the build failes with:
In file included from ../../gcc-4.4.6/gcc/ada/seh_init.c:44:
../../gcc-4.4.6/gcc/system.h:418: error: conflicting types for 'strsignal'
/nix/store/6h129q168ahnl2nzw6azr239cba884ng-glibc-2.18/include/string.h:560: note: previous declaration of 'strsignal' was here
and sometimes it doesn't. Hopefully disabling parallel builds fixes
this.

"Dzen is a general purpose messaging, notification and menuing program for X11. It was designed to be fast, tiny and scriptable in any language." -- https://github.com/robm/dzen
This can fail randomly with an error like:
building toplev.o
../../gcc-4.6.3/gcc/reload.c: In function 'find_reloads':
../../gcc-4.6.3/gcc/reload.c:3778:11: error: corrupted value profile: value profile counter (93791 out of 95865) inconsistent with basic-block count (95759)

On the plus side, this makes building GCC much faster because it
re-enables parallel building.
When building libxml2 without python enabled, pass "--with-python=no" to
configure on all systems, not only on FreeBSD. Omitting mentioned
configure option results in building libxml2 WITH python enabled. In
this case, configure is looking for python by itself in system paths.
With a rootless configuration, python includes from the host are accessed.
If those files (Python.h) are not available, building libxml2 fails.
