The library was built from https://github.com/adah1972/libunibreak without
any trouble using autogen.sh.

Compiling your test code, linebreak-test.c, though, required some extra
flags.  Most of the flags are supplied by pkg-config, so using pkg-config
in Makefile if we use this library in Tux Paint would be preferable to
directly passing `-l unibreak`.  `-l libiconv` also needed to be passed
manually but I think we already do this in Tux Paint Makefile.  The
resulting output is below.

$ gcc linebreak-test.c -o linebreak-test $(pkg-config --cflags --libs
libunibreak) -l iconv
