Remove unused header checks and defines

congigure.ac checkes for the presence of header files and creates
define indicating if it was found. Some of these defines are never
used, so the check (and the static define for Windows) can be safely
removed. This is the case for the following headers:
- langinfo.h
- libintl.h
- pthread.h
- setjmp.h
- sys/times.h
