[PATCH 1/2] Feature test macros overhaul: sparc64

[Yaakov Selkowitz <yselkowi at redhat dot com>]

sparc64 has a number of its own headers which override the generic ones.
These too need to use feature test macros properly.

These changes correspond to the generic fcntl.h and sys/stat.h changes
in commit d2df6d381b36f3f76420bc3bab965fbbdc3c3a8c and
commit 069e400c913659432c5d1953c4fa9a696b06e340.
