Laurentiu Palcu f7b44fe6db gmp: add configure.ac patch to append user provided compilation flags

gmp configure script is pretty good at auto detecting the ABI and the
tune flags that need to be passes to the compiler. However, the user
provided flags (CFLAGS, CXXFLAGS, CPPFLAGS) take precedence and the ABI
detection may fail, leading to configure errors like the one below:

| configure: error: Oops, mp_limb_t is 32 bits, but the assembler code
| in this configuration expects 64 bits.
| You appear to have set $CFLAGS, perhaps you also need to tell GMP the
| intended ABI, see "ABI and ISA" in the manual.

One solution would be to change the recipe and add the ABI manually, or
let gmp do the job.

So, this patch will:
 * allow the configure process to auto-detect the ABI and tune flags
   properly;
 * append our flags to the detected ones;

[YOCTO #5783]

README

Poky
====

Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as 
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a 
reference manual which can be found at:
    http://yoctoproject.org/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "nodistro") and contains only emulated machine support.

For information about OpenEmbedded, see the OpenEmbedded website:
    http://www.openembedded.org/

Where to Send Patches
=====================

As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.

bitbake:
    bitbake-devel@lists.openembedded.org

meta-yocto:
    poky@yoctoproject.org

Most everything else should be sent to the OpenEmbedded Core mailing list.  If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
    openembedded-core@lists.openembedded.org

Note: The scripts directory should be treated with extra care as it is a mix
      of oe-core and poky-specific files.
