Hurd port for gcc go PATCH 0-3 (9)


Hi,

Attached are patches to enable gccgo to build properly on Debian
GNU/Hurd on gcc-4.9 (4.9-4.9.0-1). With split stack enabled 95 libgo
tests PASS and 27 FAIL. Many of the failed tests do fail only in a few
sub-tests. patch0.diff is debian specific, while the rest are for
upstream.

patch0.diff is Debian specific, 
patch1.diff should be applied now when split-stack works properly.

patch0.diff: debian/rules.defs:
go_no_systems: remove gnu,
with_go: Check for DEB_TARGET_GNU_OS instead of DEB_TARGET_GNU_SYSTEM.
Otherwise kfreebsd-gnu causes go_no_systems to still be true for gnu.

patch1.diff: src/gcc/config/i386/gnu.h: Enables split stack for
GNU/Hurd. TARGET_THREAD_SSP_OFFSET is not yet supported.

patch2.diff: src/libgo/configure.ac:
Add GNU as a supported target OS for go.

patch3.diff: src/libgo/Makefile.am, src/libgo/Makefile.in
Add GNU specific go routines with the LIBGO_IS_GNU conditional.

Note: Creating the Makefile.in is hard (unnecessary) work since
automake is no longer used in the build system. Both (cd
src/libgo;automake-1.11) and (cd src/libgo;autoreconf2.64) fails. The
diff for Makefile.in was patched by hand with the aid of the diff for
Makefile.am :( This file should be possible to generate from
Makefile.am when modifying manually. In my opinion the Debian build
system is broken at least wrt libgo, since the correct version of
libtool (2.2.7a) is not available.
