However since the size of struct source_line is not fixed anymore,
iterating whole source_line should care about its size.

size if it's the last disasm_line.  But it doesn't need to be calculated

Including libio.h causes build failures on uClibc systems (which lack
libio.h).

It appears that libio.h was only included to pull in a definition for
NULL, so it has been replaced by stddef.h.

On powerpc, libio.h was conditionally included, but could be removed
completely as it is unneeded. Also, the included of stdlib.h was changed
to stddef.h (as again, only NULL is needed).

The tokens MADV_HUGEPAGE and MADV_NOHUGEPAGE are not available with
glibc 2.12 and older. Define these tokens if they are not already
defined.

This patch fixes these build errors with older versions of glibc.

Currently the -C option does not work for record command, because of the
targets mismatch when synthesizing threads.

Fixing this by using proper target interface for the synthesize
decision.

It seems gcc (4.7.2) defines _FORTIFY_SOURCE internally and becomes
confused when it sees another definition in flags.

For me, build failed like this:

CHK glibc
Makefile:548: *** No gnu/libc-version.h found, please install glibc-dev[el]/glibc-static. Stop.

and only with V=1 it printed:

<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
<stdin>:1:0: note: this is the location of the previous definition

the build with NO_NEWT=1:

This is because without NEWT support K_LEFT is #defined to -1 in
utils/hist.h

Fix it by shifting the K_LEFT/K_RIGHT #defines out of the likely range
of error values.

The %name-prefix "prefix" syntax is not available on bison 2.3 and

compatibility with older versions of bison.

There's DWARF unwind support only for x86 archs, so limit the unwind.o
object to them only.

Without this building for other archs (e.g. cross compiling for ARM) is
broken.
