NAKAMURA Takumi 495afdffd7 autoconf: Add --disable-embed-stdcxx to suppress linking libstdc++.a into llvm.dll with --enable-shared on Cygming.
Cygwin has stdc++.dll in it's distribution, and we can assume distro's stdc++.dll might be available.

NAKAMURA Takumi a1d4430cc8 tools/llvm-shlib/Makefile: Support for FreeBSD and OpenBSD.
Thanks to Yuri Gribov and Vladimir Kirillov!
*BSD(s) have environ(7) in CRT startup and cannot resolve "environ" at linking llvm.so.
environ(7) is used inlib/System/Unix/Program.inc.

Anton Korobeynikov 51b8b1d36c This patch enables ENABLE_SHARED=1 to build DLL based LLVM toolchain on MingW & Cygwin.

Daniel Dunbar 40842fa2ee build: Don't pass -avoid-version or -no-undefined on Darwin, they don't do
anything.

Jeffrey Yasskin 6b718f73a5 Try r96559 for the third time. This time the shared library is only built if
--enable-shared is passed to configure.

Jeffrey Yasskin d097117121 Oops. Pass -lgcc _only_ on ARM, not on everything except ARM.

Jeffrey Yasskin 3ac46ccdff Roll r96559 forward again, adding libLLVM-2.7svn.so to LLVM. This links 3 of
the examples shared to make sure the shared library keeps working.

Jeffrey Yasskin c451027db9 Roll back the shared library, r96559. It broke two darwins and arm, mysteriously.

Jeffrey Yasskin f750fefaf8 Add a shared library for LLVM, named libLLVM2.7svn.(so|dylib), and add an
--enable-shared configure flag to have the tools linked shared. (2.7svn is just
$(LLVMVersion) so it'll change to "2.7" in the release.)  Always link the
example programs shared to test that the shared library keeps working.

On my mac laptop, Debug libLLVM2.7svn.dylib is 39MB, and opt (for example) is
16M static vs 440K shared.

Two things are less than ideal here:
1) The library doesn't include any version information. Since we expect to break
the ABI with every release, this shouldn't be much of a problem. If we do
release a compatible 2.7.1, we may be able to hack its library to work with
binaries compiled against 2.7.0, or we can just ask them to recompile. I'm
hoping to get a real packaging expert to look at this for the 2.8 release.
2) llvm-config doesn't yet have an option to print link options for the shared
library. I'll add this as a subsequent patch.
