The usual vfork() uClibc issue. I've now reported the problem to the
uClibc developers. They ask me to see if the problem still occurs on
uClibc master, so I'm currently building a toolchain with the latest
uClibc version.

[LD]     libbtrfs.so.0.1

Trying to build a shared library in a pure static context. I'll have a
look.

I guess it's the -ldl issue investigated by Jörg?

I think we had a similar issue for a different package, but I don't
remember the details. Gustavo, maybe?

This looks like either a gcc or binutils bug. I've reported the issue
upstream as a binutils bug, see
https://sourceware.org/bugzilla/show_bug.cgi?id=17329. It's the
combination of an optimization flag, and the -g flag that causes the
issue.

Static lib issue, forgets to link with -lpthread.

I really don't know what to do about this one...

Memory allocation problem, ignore. I've modified the autobuild
infrastructure to automatically reject such build failures in the
future.

dlfcn.h usage on Blackfin FLAT. I need to finish my patch that bumps
libiscsi.

CMake package trying to build a shared library even when it's told not
to do so. Samuel?

lttng-tools. Exception added to the autobuilder script.

Samuel, this is for you.

Caused by SYS_getdents64 being not provided by the C library, because
the glibc used by the toolchain is too old. Exception added to the
autobuilder script.

Yann, maybe it would be good to see how Crosstool-NG could take into
account the various build issues that we have found, and then provide
an updated version of the toolchains.

Another stupid CMake based package building a shared library when told
not to do so. Samuel? :-)

Maybe Blackfin doesn't provide the atomic compiler intrinsics?
