Internal toolchain is never used for nios2:

 config BR2_TOOLCHAIN_BUILDROOT
        bool "Buildroot toolchain"
-       depends on !BR2_microblaze && !BR2_aarch64
+       depends on !BR2_microblaze && !BR2_aarch64 && !BR2_nios2

this was in 830205c0361c751c39fabeb1366100e2a94a27a4, which comes from
you :-)

Indeed most of the issues are caused by the lack of libffi support:

+--------------------------+-----+
| reason                   | cnt |
+--------------------------+-----+
| libffi-3.0.13            |  28 |
| aiccu-20070115           |  10 |
| binutils-2.21            |   9 |
| libnspr-4.9.6            |   1 |
| e2fsprogs-1.42.8         |   1 |
| libnetfilter_queue-1.0.2 |   1 |
+--------------------------+-----+

but there's also a bunch of other problems as you can see. For the time
being, I've modified the autobuilders script to avoid any configuration
that involves libffi on nios2. Since the nios2 support in libffi has
recently been contributed, they will hopefully make a new release in
the near future.

It wasn't implemented until I received your e-mail, but it's now done.

Hopefully :-)
