Here's the config.log contents:

I disabled _FORTIFY_SOURCE because it caused an error. But I'm completely clueless as to what might be wrong.

(I am aware of this post, suggesting to --disable-sanity-checks)

Configure doesn't fail if I remove linuxthreads(2.3) from the source folder.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU C Library configure (see version.h), which was
generated by GNU Autoconf 2.68.  Invocation command line was

  $ /home/ubuntu/Downloads/glibc-2.16.0/configure --enable-add-ons --disable-sanity-checks CPP=gcc -E -D_FORTIFY_SOURCE=0 -U_FORTIFY_SOURCE

This was caused by the fact that the only line in linuxthreads's configure file was exit 0 (which obviously caused the whole script to stop as it was read).

What I did was change linuxthreads's configure content to libidn's configure content:

libc_add_on_canonical=
libc_add_on_subdirs=.
