function descriptors used by Go, and ffi_call_go sets up
the static chain parameter for calling a Go function.
The entry points are disabled when a backend has not been
updated, much like we do for "normal" closures.

Only run the complex type tests on supported platforms.

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.
