Disable zlib features in LLVM shared lib builds to avoid dependency.
Disable zlib features in LLVM shared lib builds to avoid dependency.

lib/DebugInfo/DwarfContext.cpp now references zlib.

ChromeOS chroot doesn't have the 32-bit libz.  Unclear if users will have it.
Not changing the sandboxed translator build, since that is static
and I assume the configure step won't detect a static zlib.

TEST=ldd:
	linux-gate.so.1 =>  (0xf77a9000)
	libLLVM-3.3.so => /usr/local/google/home/nacl1/native_client/toolchain/pnacl_linux_x86/host_x86_32/bin/../lib/libLLVM-3.3.so (0xf5d73000)
	libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf5d37000)
