package/tar: properly handle autoreconf

Browse Source 
Commit 9a66711be1 ("package/tar: fix
linking with libiconv") added two patches that patch Makefile.am
files, but it forgot to add TAR_AUTORECONF = YES.

However, a gotcha is that TAR_AUTORECONF = YES would apply to both the
target tar, but also the host tar. But for host-tar, we can't accept
to do an autoreconf, because this would cause host-tar to have a
dependency on host-{autoconf,automake,libtool}, which in turn would
have a dependency on host-tar.

Since anyway the patches 0002/0003 that modify Makefile.am are only
useful to fix a libiconv problem that occurs when building target tar,
we disable autoreconf for host-tar, and we prevent automatic
autoreconf by touching the right Makefile.in files. This mess can be
dropped next time we update tar, as 0002/0003 will be part of the next
tar release.
