Bug#783236: fails to build stage1 cross compiler: "libcc1plugin.so not found"
Source: gcc-5
Version: 5-20150321-1
Tags: patch
User: helmutg@debian.org
Usertags:rebootstrap
The libcc1 issue did not go away entirely yet. Even though it is no
longer installed for cross compilers to use the native libcc1 instead,
the stage1 compiler still tries to install it (even though I can hardly
come up with a way of using it there). Long story short, the symptom is:

Looking a bit up in the build log reveals where it really went:
| libtool: install: /usr/bin/install -c .libs/libcc1plugin.so.0.0.0 /tmp/buildd/gcc_1/gcc-5-5.1~rc1/debian/tmp/usr/lib/gcc/aarch64-linux-gnu/5/plugin/libcc1plugin.so.0.0.0
| libtool: install: (cd /tmp/buildd/gcc_1/gcc-5-5.1~rc1/debian/tmp/usr/lib/gcc/aarch64-linux-gnu/5/plugin && { ln -s -f libcc1plugin.so.0.0.0 libcc1plugin.so.0 || { rm -f libcc1plugin.so.0 && ln -s libcc1plugin.so.0.0.0 libcc1plugin.so.0; }; })
| libtool: install: (cd /tmp/buildd/gcc_1/gcc-5-5.1~rc1/debian/tmp/usr/lib/gcc/aarch64-linux-gnu/5/plugin && { ln -s -f libcc1plugin.so.0.0.0 libcc1plugin.so || { rm -f libcc1plugin.so && ln -s libcc1plugin.so.0.0.0 libcc1plugin.so; }; })
To me it seems that the simplest way to fix this build failure is to
simply update cross-install-location.diff and have it install the unused
libcc1plugin.so. Do you agree?
