Also some style cleanup.
Note that defining an empty-string variable *does* change the hash.
I would like to change this behaviour one day
(clean up attrs when compiling the derivation).
From https://lists.macosforge.org/pipermail/macports-dev/2011-July/015263.html:
5) Building with a compiler that doesn't support newer __builtins
If your port uses MacPorts compilers rather than the default compiler,
you may run into trouble with string functions. You'll see errors at
link time about undefined __builtin_* functions. If this happens, you
may want to compile with -D_FORTIFY_SOURCE=0 to tell the headers to
use unfortified versions which do not use compiler builtins.
This also fixes the annoying issue that minicom doesn't work out of the
box:
$ minicom
minicom: there is no global configuration file /etc/minirc.dfl
Ask your sysadmin to create one (with minicom -s).
$ sudo minicom -s
minicom: there is no global configuration file /etc/minirc.dfl
Ask your sysadmin to create one (with minicom -s).
minicom 2.4 basically refuses to enter setup unless /etc/minirc.dfl
already exists. sudo touch /etc/minirc.dfl is enough to fix that though,
but with this commit "sudo minicom -s" will work out of the box.
This is in order to prepare for fetching the build output from the corresponding
target machine to even further speed up deployment.

This should prevent some annoying messages such as:

This fixes a bunch of issues for the NixOps Hetzner backend, because over there,
it's quite difficult to export the references graph without either duplicaing
lots of code or make a bunch of workarounds.
A detailed description about how it works can be found in the
meta.longDescription attribute.
