Is this really needed?

This is the default (unneeded).

You may want to use --disable-all

Does --disable-programs not work?

> --disable-protocols

Does --disable-everything not work?

These look useless.

Since you also used --disable-debug I 
have to ask if you try to produce a 
useless library (no debug information, 
but no optimizations either)?
If you have a good reason, --disable-asm 
is probably simpler.

What does git log say about the version you are testing?
