Thomas Petazzoni 7f1088f9ca package/tar: allowing building even on non-Y2038 compliant systems
Since the bump of tar to version 1.35 in Buildroot commit
d4d483451f ("package/tar: security bump
to version 1.35"), the build will fail on systems that are not Y2038,
such as uClibc configurations.

In order to preserve the previous behavior, pass --disable-year2038.
See the gnulib documentation for details [0]. Contrary to what the
option name might suggest, it doesn't really disable Y2038 support,
but only the check that the system is Y2038 compliant. So even with
--disable-year2038, if the system is Y2038 compliant (uses a 64-bit
arch, uses the musl C library, or uses the glibc C library with
BR2_TIME_BITS_64=y), tar will be Y2038 compliant.
