I've tried building a small agent for MIPS with net-snmp 5.1.4 and it worked
like a breeze for me. In fact, I had problems with 5.4.x versions, and they
were larger agents anyway. I needed net-snmp for v2 trap generation only, and I
was able to reduce the snmpd + all the required .so files to about 450kb.
Also, these files weren't stripped, so maybe if you strip them, you can reach
~ 300kb for the entire agent
The configure options I used are almost exactly the ones Magnus specified.

Try using HEAD, 5.4.x could work as well.

No, it is annoyingly enough missing and it is nontrivial to introduce
it. I would love to be able to specify --with-out-snmp :-)

Removing just v1 gives me 788 bytes in text size and 652 bytes in file
size. Given that this is less than 0.5% I'd say it isn't worth the
trouble.
When I wish to build a really stripped down net-snmp then I use the
following command:
../net-snmp/configure --enable-mini-agent --without-rpm
--without-kmem-usage --without-root-access --with-defaults
--prefix=/tmp/net-snmp-install --disable-debugging --disable-mib-loading
--disable-applications --disable-manuals --disable-scripts
--with-out-mib-modules=snmpv3mibs,mibII/vacm_vars --disable-privacy
--disable-md5 --disable-shared --with-out-transports=TCP,Unix,Callback
--without-openssl --with-cflags=-Os

I am too young to be able to answer that.
