Can we do that *at*least* for x86_64-linux? 

On the TL list we got another report about that, it seems that RH something
does not ship expat.so.1, so we are hosed here. That would be a pain.

I have built xetex and the libs are the same without expat, but it adds
so I am not happy about that, too.

Who else can build on an old x86_64-linux machine and check 
afterwards with
	strings -a xetex | grep '\.so'

Pity. Strange enough the freetype etc links are anyway not included, only
in my case, which is reasonable.
