            Bug ID: 62260
           Summary: Build inside source tree doesn't work with lto-plugin
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hjl.tools at gmail dot com

When GCC is configured inside source tree with

./configure --enable-languages=c,c++ --disable-bootstrap

liblto_plugin.la is installed at the wrong place:

ibtool: install: /usr/bin/install -c .libs/liblto_plugin.so.0.0.0
/export/gnu/import/git/gcc/host-x86_64-unknown-linux-gnu/lto-plugin/../host-x86_64-unknown-linux-gnu/gcc/liblto_plugin.so.0.0.0

It should be installed at
/export/gnu/import/git/gcc/host-x86_64-unknown-linux-gnu/lto-plugin/../../host-x86_64-unknown-linux-gnu/gcc/
