lightning: new package 

GNU lightning is a library that generates assembly language code at
run-time.

https://www.gnu.org/software/lightning/



[Thomas:
 - Wrap list of architectures in Config.in
 - Introduce an explicit Config.in option for the disassembler
   support, since it needs both binutils and zlib, which may not be
   easy to guess.
 - Add hash file.
 - Bump to version 2.0.5.
 - Add patch to fix cross-compilation issues on ARM and x86 due to
   AC_RUN_IFELSE() tests.
 - Adjust license information: the library is actually under LGPLv3+,
   not GPLv3. There is a COPYING file with the text of the GPLv3 in
   the code base, but this license doesn't seem to be used in anything
   that is actually installed.
 - Add AUTORECONF = YES since we're now patching configure.ac.
 - Add missing dependency on zlib for the disassembler support.
 - Add a special LIBS=-lintl when enabling the disassembler support
   because binutils libraries use gettext functions, but they are not
   linked against libintl.]
