Correct solaris libc definitions:

* pthread_t is defined as uint_t, so must be c_uint, not uintptr_t, just
  as pthread_key_t is already defined
* fd_set is defined as long, so must be i32/i64 based on
  target_pointer_width; this also fixes an indirect endianness issue
  encountered on sparc
* FD_SETSIZE should be defined as 65536 when target_pointer_width = 64

Fixes #515
