0d23a5c1b1 [BZ #16046] Static dlopen correction fallout fixes.
Fixes to address issues from BZ #15022 resolution, as follows:

* TLS updates to csu/libc-tls.c -- we now have a proper main map, so
  there's no longer a need to create a separate fake one to keep TLS
  structures,

* random updates to elf/dl-close.c -- LM_ID_BASE is now a valid name
  space ID for static executables as well, so assert that we don't
  unload the main map.  Similarly dl_nns isn't supposed to be 0 for
  static executables anymore,

* actual BZ #16046 fix to elf/dl-iteratephdr.c -- the dl_iterate_phdr
  special function for static executables isn't needed anymore, provided
  that l_phdr and l_phnum members of the main map have been properly
  initialized (done in _dl_non_dynamic_init in elf/dl-support.c now),

* ld.so.cache loader update to elf/dl-load.c --
  GL(dl_ns)[LM_ID_BASE]._ns_loaded is now always initialized in static
  executables so can become the fallback loader map to check for
  DF_1_NODEFLIB, provided that the l_flags_1 member of the main map has
  been properly initialized (done in elf/dl-support.c now); this also
  ensures previous semantics elsewhere in elf/dl-load.c,

* matching updates to elf/dl-support.c -- to complement the two fixes
  above.

409e00bd69 Disable x87 inline functions for SSE2 math
When i386 and x86-64 mathinline.h was merged into a single mathinline.h,
"gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse
and SSE2 is enabled.  It is a regression on x86-64.  We should check
__SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions.

d7b00f9810 Fix invalid memory access when parsing netgroup files with blank lines (BZ #16506)
The netgroups file parsing code tries to access the character before
the newline in parsed lines to see if it is a backslash (\).  This
results in an access before the block allocated for the line if the
line is blank, i.e. does not have anything other than the newline
character.  This doesn't seem like it will cause any crashes because
the byte belongs to the malloc metadata block and hence access to it
will always succeed.

There could be an invalid alteration in code flow where a blank line
is seen as a continuation due to the preceding byte *happening* to be
'\\'.  This could be done by interposing malloc, but that's not really
a security problem since one could interpose getnetgrent_r itself and
achieve a similar 'exploit'.

The possibility of actually exploiting this is remote to impossible
since it also requires the previous line to end with a '\\', which
would happen only on invalid configurations.

af37a8a349 Avoid undefined behaviour in netgroupcache
Using a buffer after it has been reallocated is undefined behaviour,
so get offsets of the triplets in the old buffer before reallocating
it.

47590bce28 ARM: Fix clone build for ARMv4
ARMv4 does not have the blx instruction, so use the BLX macro which
handles abstracting this for us.

	[BZ #16499]

	of blx instruction directly.

5d41dadf31 Adjust pointers to triplets in netgroup query data (BZ #16474)
The _nss_*_getnetgrent_r query populates the netgroup results in the
allocated buffer and then sets the result triplet to point to strings
in the buffer.  This is a problem when the buffer is reallocated since
the pointers to the triplet strings are no longer valid.  The pointers
need to be adjusted so that they now point to strings in the
reallocated buffer.

e68485398b S/390: Increase tst-tls7 test case timeout
TLS in a dlopened object works fine when accessed from a signal
handler. The default kernel scheduling parameters prevents the
testcase to finish within the 4 seconds.

Tested the bigger timeout on s390 and s390x.

d98720e07f PowerPC: Fix gettimeofday ifunc selection
The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where
__vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal
version used within GLIBC) to use the system call version instead of the vDSO one.
This patch changes the check if vDSO is available to get its value directly
instead of rely on __vdso_gettimeofday.

This patch changes it by getting the vDSO value directly.

It fixes BZ#16431.
