'all' is the conventional target for building everything in the
makefile, but the child make was expecting all-$(target), for debugging
reasons that I don't recall exactly. Restore the expected behavior.

This adds the magic .note.GNU-stack section at the end of each ARM
asm file (when built with gas), indicating that a non-executable
stack is allowed.
Without this section, the linker will assume the object requires an
executable stack by default, forcing an executable stack for the
entire program.

Adds following targets to configure script to support RVCT compilation
without operating system support (for Profiler or bare metal images).
- armv5te-none-rvct
- armv6-none-rvct
- armv7-none-rvct
To strip OS specific parts from the code "os_support"-config was added
to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS
specific parts such as OS specific includes and function calls for
timers and threads etc. This was done to enable RVCT compilation for
profiling purposes or running the image on bare metal target with
Lauterbach.
Removed separate AREA directives for READONLY data in armv6 and neon
assembly files to fix the RVCT compilation. Otherwise
"ldr <reg>, =label" syntax would have been needed to prevent linker
errors. This syntax is not supported by older gnu assemblers.

Solaris 10 requires -lposix4 to build successfully on gcc. I only have a
Sparc machine to test with on Solaris 10, but this change leaves
OpenSolaris x86 in a usable state w/ gnu-generic.
I am of the belief that this change should fix Solaris 10 on Sparc, but
will leave other Solaris architectures as is. If someone has an x86
Solaris 10 machine to test on, they may add x86-solaris-gcc to
libvpx/configure and give it a go.

Fix out-of-tree builds using NASM. NASM expects its include paths to
have a trailing slash. These aren't used used when doing in-tree builds
(./configure)
Change-Id: I38d469d15acb1b7e65733a2e5ca8c9d86fa4ad86
yasm has to be preferred as currently nasm produces marginally less
efficient code (longer opcodes). Filed for nasm as:
https://sourceforge.net/tracker/?func=detail&atid=106208&aid=3037462&group_id=6208
OTOH package should be built always the same, no matter which additional
packages are / are not present on the system. As the package should be
built with nasm (as yasm may not be available) we should not use yasm
even if it is possibly available.
nasm >= approx. 2.09 is required for the nasm compilation as the former
versions had a section alignment bug.
Provide nasm compatibility. No binary change by this patch with yasm on
{x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on
{x86_64,i686}-fedora13-linux-gnu have been checked as safe.

The regex which postprocesses the gcc make-deps (-M) output was too
greedy and matching in the dependencies part of the rule rather than
the target only. The patch provided with the issue was not correct, as
it tried to match the .o at the end of the line, which isn't correct
at least for my GCC version. This patch matches word characters
instead of .*
Thanks to raimue and the MacPorts community for isolating this issue.

Using uname fails e.g. on a 64-bit machine with a 32-bit toolchain.
The following gcc -dumpmachine strings have been verified:
* 32-bit Linux gives i486-linux-gnu
* 64-bit Linux gives x86_64-linux-gnu
* Mac OS X 10.5 gives i686-apple-darwin9
* MinGW gives mingw32
*darwin8* and *bsd* can safely be assumed to be correct, but *cygwin*
is a guess.

This patch adds support for building shared libraries when configured
with the --enable-shared switch.
Building DLLs would require more invasive changes to the sample
utilities than I want to make in this patch, since on Windows you can't
use the address of an imported symbol in a static initializer. The best
way to work around this is proably to build the codec interface mapping
table with an init() function, but dll support is of questionable value
anyway, since most windows users will probably use a media framework
lib like webmdshow, which links this library in staticly.

This renames the vpx_codec/ directory to vpx/, to allow applications

Split the 'make install' target into two: install and dist. dist
