Adding support for building QEMU for Windows

This series enables a number of packages and dependencies to be built for mingw32. The goal is to enable the building and packaging of QEMU targeting mingw32 with support for SDL/VNC enabled as well as being able to execute the qemu* machines of oe-core/meta.

The following series fixes a number of issues with compilation of certain components that are required to build and distribute QEMU. This series includes:

* Enabling 'secure-api' for mingw-w64-headers
* Fix/enable building of shared libraries for gettext
* Work around to avoid dependency on bash for glib-2.0, clean up of some glib-2.0 appends which are resolved in oe-core meta
* Better packaging of libgcc for easy use on Windows (deploy dll to bindir)
* Updating FILES_* to support locations for mingw32 output (bindir contains .dll) for libgcc, expat, libpcre, gettext, glib-2.0, libsdl, libgpg-error and libgcrypt
* Addition of PACKAGECONFIG options to libsdl, and configuring of PACKAGECONFIG for libsdl, glib-2.0 and libgcrypt to handle Windows only features and or ability to disable features that do not support mingw32/Windows
* Enabling build of libfdt in the dtc recipe, but skipping dtc itself
* Fixes for configuring libgpg-error and libgcrypt when targeting mingw32

The intended build execution is to allow for 'buildtools-tarball' (or any populate_sdk target with 'nativesdk-qemu' in TOOLCHAIN_HOST_TASK) to create an output that includes all dependent nativesdk binaries as well as a nativesdk QEMU binaries. This series does not however address fixing the environment setup script or self-extracting installer shell script that is normally provided by buildtools-tarball.

This series with the multiple oe-core/meta series was tested on the following target Windows platforms: Windows 10 (64-bit), Windows 8.1 (64-bit) and Windows 7 SP1 (64-bit).

The changes were also tested on the following Linux build hosts: Debian 8 (64-bit), Ubuntu 16.04 (64-bit), CentOS 7 (64-bit).

For convenience this series is also available in the git repository:

https://github.com/nathanrossi/meta-mingw nrossi/mingw-qemu-v2

This series partly depends on a set of series for oe-core/meta. The following series are required for building of QEMU (but not all parts of this series specifically), including dll packaging detection and libgcrypt support:

https://patchwork.openembedded.org/series/5050/
https://patchwork.openembedded.org/series/5051/
https://patchwork.openembedded.org/series/5052/
https://patchwork.openembedded.org/series/5053/

A branch which has the series above merged has been published to allow for easy testing, it is available at:

Changes v2:
* Moved a number of patches from oe-core series to this series
* Updated cover letter to reflect series additional inclusion
* Bring cover letter info from oe-core/meta series
* Updated commit messages

2.11.0

Add the 'secure-api' PACKAGECONFIG and enable it by default. The 'secure-api' feature enables the secure string functions that are provided in the MS C Runtime e.g. "strerror_s".

These functions are needed for glib-2.0 compilation.

Sorry this should have v2 in the subject. I realized just as the second patch was sent. I've resent with v2 for clarity.
