The above software uses the target triplet from `cc -dumpmachine` as a
binary compatibility check. However, on darwin, the output includes the
darwin version number, which leads to build failures against a binary
skalibs package built a different version of darwin than the current
system.
Explicitly setting target ensures code can be compiled against a skalibs
binary built on a different version of darwin.

The $lib output refers to the terminfo database in $out, which is about
10x larger than the ncurses shared library. Splitting these outputs
saves a small amount of space for any derivations that use the terminfo
database but not the ncurses library, but we do not have evidence that
any such exist.
The following parameters are now available:
* hardeningDisable
To disable specific hardening flags
* hardeningEnable
To enable specific hardening flags
Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.
cc-wrapper supports the following flags:
* fortify
* stackprotector
* pie (disabled by default)
* pic
* strictoverflow
* format
* relro
* bindnow
New features
------------
* Processes under PRoot now appear with their real names, that is,
they are not renamed ld-linux.so or prooted-... anymore.
* Own ELF loader.
Fixes
-----
* Most bugs related to shebang support -- ie. #! at the beginning of
a program -- were fixed.
* It is now possible to use GDB against multi-threaded programs under
PRoot x86_64 and x86.
* It is possible to execute x86_64 programs from x86 programs again.
* It is possible to use x86 ptrace-based programs (strace, gdb, ...)
under PRoot x86_64 again.
* The loader is now built with the build-id linker option explicitly
disabled. This special section might interfere with loaded
programs.
* The loader can now load relocatable objects that have a predefined
base address.
