Fix for x32 by removing 'q' suffix in x86-64 instructions

We do not need the 'q' suffix on x86_64 atomic instructions for AO_t
which is defined as "unsigned long"; the later is 32-bit for x32
and 64-bit for x86-64; the register operand in x86-64 atomic
instructions is sufficient to properly determine the register size.

* src/atomic_ops/sysdeps/gcc/x86_64.h (AO_fetch_and_add_full,
AO_and_full, AO_or_full, AO_xor_full, AO_compare_and_swap_full,
AO_fetch_compare_and_swap_full): Remove 'q' suffix in asm instruction.

Fix autogen.sh to prevent reporting success if autoreconf failed

* autogen.sh: Add "set -e" command to abort script execution on
autoreconf failure (thus not printing "ready" in that case).

whether GCC -fPIC option causes __PIC__ macro definition; pass
-D __PIC__ to PICFLAG (instead of CFLAGS) only if not defined
automatically in case -fPIC specified; update comment.

Update ChangeLog

Fix double_ptr_storage definition for GCC pre-v4 (x86_64)

* src/atomic_ops/sysdeps/standard_ao_double_t.h: Do not use __m128
if GCC pre-v4 (at least, xmmintrin.h is missing in gcc-3.4.3-x86_64
included in Solaris 10 distribution).
