>Description:
	When trying to extract a file compressed in the xz format,
	/usr/bin/xz fails with the message

	/usr/bin/xz: mpfr-3.0.0.tar.xz: Compressed data is corrupt

	Since the file as downloaded from the internet passes both the
	MD5 and SHA256 checksum test (and decompesses correctly on a
	amd64 linux machine with the same version of the xz utility),
	I assume that there are some portability issues which should
	be addressed.

>How-To-Repeat:
	Execute on a sparc64 box:

	fetch  http://www.mpfr.org/mpfr-current/mpfr-3.0.0.tar.xz
	xz -d mpfr-3.0.0.tar.xz
>Fix:

	Apart from decompressing the file somewhere else, I do not
        know how to fix this.
