There is indeed no liblto_plugin.so found in my build tree.

[Bug bootstrap/45174] Make fails in zlib
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45174 John Tytgat changed: What|Removed |Added CC||John.Tytgat at aaug dot net --- Comment #26 from John Tytgat 2011-01-18 01:15:57 UTC --- I'm seeing the same problem with gcc 4.6 trunk (r168937) for building a cross compiler with target arm-unknown-eabi configured with newlib in tree. The crucial bit is --enable-multilib, without this option the problem is not reproducible. It looks like the --enable-multilib enables building the multilibs of the host (instead of the target) for zlib. In my case the host is (on Ubuntu 10.04): $ gcc -dumpmachine x86_64-linux-gnu $ gcc -print-multi-lib .; 32;@m32 I've attached my buildlog and the full content of gcc builddir subdirectories 'zlib' and '32/zlib' (the latter not present when --enable-multilib is omitted). Also like the original bug reporter is saying: I can avoid this problem by specifying --with-system-zlib.
