  Add OpenRISC support This patch adds support for the OpenRISC architecture. (http://opencores.org/or1k/Main_Page) This patch has been tested under Linux with QEMU-user emulation support. - 32 Bit - big endian - delayed instructions This is the only available configuration under Linux. The description of the ABI can be found on the official website. Is passes the testsuite except of the unwindtest_ffi_call.cc testcase, which seems to be a problem of gcc and not libffi. Some testcases of the gcc testsuite still fail. Signed-off-by: Sebastian Macke <sebastian@macke.de>
