Change request of devel/autoconf to use .tar.gz

["OBATA Akio" <obache%netbsd.org@localhost>]

Hi,

Is it reasonable that devel/autoconf is changed to back using .tar.gz instead 
of .tar.xz?

* not negligible package require devel/autoconf to build
* autoconf require archivers/xz because it is using .tar.xz distfile
* xz is marked as "GCC_REQD=3.4"

I don't want to install gcc34 from pkgsrc for just require autoconf.

Default compiler of Haiku R1 alpha1 is gcc-2.95.3.
I'm not sure if gcc-3.4 from pkgsrc works on Haiku or not.
Default compiler of Interix-6.0 is gcc-3.3,
and lang/gcc34 is marked as "NOT_FOR_PLATFORM=Interix-*-*".
