Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction
struct to pass conform tests, but it ended up also changing the ABI for
32 bit builds.  For 64 bit builds, changing the long to two ints works,
but for 32 bit builds, it inserts 4 extra bytes.  This leads to many
packages randomly failing like bash that spews things like:
	configure: line 471: wait_for: No record of process 0

Bracket the new member by a wordsize check to fix the ABI for 32bit.

	* sysdeps/unix/sysv/linux/sparc/bits/sigaction.h
	(struct sigaction): New struct member __glibc_reserved0, change
	type of sa_flags to int.

This patch completes the headers cleanup consequent on removal of
_BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations):

* #endif conditionals that referred to BSD or SVID are updated.

* Redundant __USE_* tests in cases involving __USE_MISC are removed.
  This includes cases such as __USE_MISC || __USE_ISOC99, where
  __USE_MISC is redundant (because __USE_MISC is only ever defined in
  the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99
  is also defined; the same applies to the non-XSI-extended POSIX
  versions), and cases involving __USE_GNU, where __USE_GNU is
  redundant (because if __USE_GNU is defined, so are the other __USE_*
  macros).  There may well be other cases of __USE_FOO || __USE_BAR
  tests that could be simplified because one macro implies the other;
  this patch only addresses cases involving __USE_MISC.

Tested x86_64.
