Nick Wellnhofer 84a4f84c1c build: Don't check for required headers and functions
Unless we are on Windows, the following POSIX headers are required.
They're part of the earliest POSIX specs and it doesn't make sense to
check for them.

- fcntl.h
- unistd.h
- sys/stat.h
- sys/time.h

On Windows, io.h, fcntl.h and sys/stat.h are always available.
