xz in base system trouble on MIPS

[Milan Obuch]

Hi,

I am trying to test various system parts and ports building on my RSPRO. There 
is a problem with xz as compiled with base system - trying to build misc/mc 
gives 'unknown file format' error on /usr/ports/distfiles/mc-4.7.4.tar.lzma 
tarball. After commenting out IGNORE line in archive/xz Makefile, compilling, 
installing the port and 'cp /usr/local/bin/xz /usr/bin/xz' this error is gone.

What could be root cause of this? As both base system and ports xz is version 
5.0, I think there must be some error in base system integration or some 
tweaking is not done...

Regards,
Milan
