AMD GCN Port contributed by Andrew Stubbs <ams@codesourcery.com> Add support for the AMD GCN GPU architecture. This is primarily intended for use with OpenMP and OpenACC offloading. It can also be used for stand-alone programs, but this is intended mostly for testing the compiler and is not expected to be useful in general. The GPU architecture is highly parallel, and therefore Newlib must be configured to use dynamic re-entrancy, and thread-safe malloc. The only I/O available is a via a shared-memory interface provided by libgomp and the gcn-run tool included with GCC. At this time this is limited to stdout, argc/argv, and the return code.

newlib: migrate from INCLUDES to AM_CPPFLAGS Since automake deprecated the INCLUDES name in favor of AM_CPPFLAGS, change all existing users over. The generated code is the same since the two variables have been used in the same exact places by design. There are other cleanups to be done, but lets focus on just renaming here so we can upgrade to a newer automake version w/out triggering new warnings.

Add gfortran support for AMD GCN From: Kwok Cheung Yeung <kcy@codesourcery.com> This patch adds enough support for constructors/destructors and OS functions to be able to link and run gfortran programs on AMD GCN. There's no actual ability to do I/O operations on this targets, besides "write" to stdout and stderr, so most of the functions are just stubs.

require autoconf-2.69 exactly The newlib & libgloss dirs are already generated using autoconf-2.69. To avoid merging new code and/or accidental regeneration using diff versions, leverage config/override.m4 to pin to 2.69 exactly. This matches what gcc/binutils/gdb are already doing. The README file already says to use autoconf-2.69. To accomplish this, it's just as simple as adding -I flags to the top-level config/ dir when running aclocal. This is because the override.m4 file overrides AC_INIT to first require the specific autoconf version before calling the real AC_INIT.
