xz: Rename a variable to avoid a namespace collision on Solaris.

Browse source 
I don't know the details but I have an impression that there's
no problem in practice if using GCC since people have built xz
with GCC (without patching xz), but renaming the variable cannot
hurt either.

Thanks to Mark Ashley.
