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.

Replace =1 with =true for yasm tool element. This aids in upgrading
e.g., vs9 project files to vs10.
build/x86-msvs/yasm.xml generated during conversion will require the
Separator attribute to be removed for the build to complete
successfully.

- Updated -linux-rvct targets to support RVDS 4.0 and later.
- Changed optimization flag to -Otime because -O3 ruined performance
for RVCT linux targets.
- Added support for --enable-small for RVCT
- RVCT created library should be able to link with GCC
- Supports building shared linux libraries

Always use CFLAGS/LDFLAGS that point to headers and libvpx.a inside our
build tree before ones from the environment, which could reference
headers or libs outside the build tree.
This fixes issue 307.

"Favor fast code(/Ot)".

According to the docs, this should have been enabled, but
the disassembled output shows otherwise. This improved

Detect the number of available cores and limit the thread allocation
accordingly. On decoder side limit the number of threads to the max

Enable extraction of assembly offsets from compiled examples in MSVS.
This will allow us to remove some stub functions from x86 assembly since
we will be able to reliably determine structure offsets at compile time.

vpx_scale/arm/neon/

AMD64 only implies SSE2, not SSE3. There aren't any known cases where
icc was generating SSE3 instructions since all the vectorizable code
is already in handwritten asm, so this fix is included mostly for
correctness. Fixes issue #259.

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.
