[QE-users] OPENMP preprocessor tag

[Paolo Giannozzi]

Hi, the __OPENMP preprocessing variable, with two underscores, has been
superseded by _OPENMP, with one underscore. All OpenMP-aware compilers
should automatically set _OPENMP. The contents of include/defs.h.README was
obsolete and has been updated recently.
