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.

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)".

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.

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.
