For what it's worth, on my system, this exact set of commands produces
a working build, which includes avahi.

This path seems to indicate that you might be running Buildroot as
root. You should not do this.

And in fact I think it's precisely because you're building somewhere
in /usr that things break. In order to workaround libtool oddness, we
have a mechanism in Buildroot that modifies .la files by replacing:

 /usr

by

 $(STAGING_DIR)/usr

But in your case, since your $(STAGING_DIR) starts by /usr, the rule
gets executed over and over and over again, so the path goes like this:

 /usr
 $(STAGING_DIR)/usr
 $(STAGING_DIR)/$(STAGING_DIR)/usr
 $(STAGING_DIR)/$(STAGING_DIR)/$(STAGING_DIR)/usr

etc.

So as a quick fix you can just not build from /usr, and build from
$HOME, as a normal user. Long term, we should improve our sed
expression to not fall into this.

Regards,

Thomas
