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.
Bugfix release; released on February 22 2016:
- Fix argument checks for interpreter invoke with `-m` and `-c`
on Windows.
- Fixed a bug that cased locale detection to error out on Python 3.
Re-builds many Python packages, but no new failures on x86-64.
Find-tarballs was failing on some `requireFile` that was fixed-output
but didn't specify `outputHashMode`. Apparently, nix is fine with that
and uses the "flat" default, although that's undocumented.
