patches to make jdk8 build on NetBSD

[Christos Zoulas]

Hello,

1. get rid of -gstabs; stabs don't work together with pre-compiled-headers
   and gcc anymore. Makes the code a lot simpler!
2. define __STDC_LIMIT_MACROS early so that other headers that include
   <stdint.h> by side effect define the necessary macros.
3. remove stray <fcntl.h> include. This is not used at all in this file;
   it looks out of place anyway :-)

Best,

christos
