Yeah, but libgnutls-extra should be linked to libgnu:

libgnutls_extra_la_LIBADD += ../gl/libgnu.la ../lib/libgnutls.la

And libgnu should be linked to liblgnu:

libgnu_la_LIBADD += ../lgl/liblgnu.la

And libgnu seem to contain read_binary_file:

jas at mocca:~/src/gnutls$ objdump -t gl/.libs/libgnu.a | grep read_binary_file
000001f8 g     F .text  00000034 read_binary_file
jas at mocca:~/src/gnutls$

So libgnutls-extra should pick it up.  But you'll have to re-link
libgnu if you don't build from a clean directory.
