Details:

When attempting to install Octave in my home directory (I don't have root
access), the usual "configure; make install" failed for me with errors about
linking to many zlib functions (gzputc, et al.)

Adding a -lz to the LIBS variable in src/Makefile, changing it from
LIBS = -lm
to
LIBS = -lm -lz
, led to a successful install.

The makefile includes a substitution step to replace
%OCTAVE_CONF_Z_LIBS%
with the appropriate thing (Z_LIBS = -lz), but I'm unclear where that
substitution happens.

What worked for me in the end:

./configure --prefix=$HOME/tech/root --disable-readline
sed -i '/^LIBS =/s/$/ -lz/' src/Makefile
make install
