package/xz: fix musl static build

Runnning autoreconf is needed to avoid the following static build
failure on musl which is raised as otherwise LDFLAGS (which contains
-static) is not passed:

/home/autobuild/autobuild/instance-16/output-1/host/lib/gcc/armeb-buildroot-linux-musleabi/13.3.0/../../../../armeb-buildroot-linux-musleabi/bin/ld: /home/autobuild/autobuild/instance-16/output-1/host/lib/gcc/armeb-buildroot-linux-musleabi/13.3.0/libgcc.a(_dvmd_lnx.o): in function `__aeabi_idiv0':
/home/autobuild/autobuild/instance-16/output-1/build/host-gcc-final-13.3.0/build/armeb-buildroot-linux-musleabi/libgcc/../../../libgcc/config/arm/lib1funcs.S:1499:(.text+0x8): undefined reference to `raise'

This build failure is raised by autobuilders since bump to version 5.6.2
in commit d1d77eb274 but it can also be
reproduced on version 5.4.7 (but not on 5.4.6). There is probably an
issue with these two official autotools tarballs which have been
released the same day (on May 29 2024).
