That's right. The file is generated from libopts.def in the same 
directory. I now looked at the code finally :) and I think it's better 
to leave the POSIX_SHELL variable alone (and not set it from the recipe 
either because it has no effect), and go back to the original idea of 
patching the place where it's used to make a shebang line - I think 
there's only one such place in the source code.

But fixing libopts.def is okay too, I just think it's more trouble.
