I forgot to post it here, but the problem I had was in libz (thanks to 
Luke for some tips). When I used system's libz then the problems went 
away. I suspect the supplied libz is miscompiled in some way, however I 
had no time yet to track it down exactly.

Heh, I suspect it's the same code that my g77 cross-compiler hates, as 
I posed here few days ago ... got no response so far :/

That's the libz thing: what happens is the following: first load opens 
the file as gzip, that should work, but for some reason it doesn't, so 
load falls back to raw mode and tries to read it as-is, however then 
the magic number is bogus since it's actually gzipped, so load fails. 
If you use system's libz the file is decompressed correctly.
