Provide the path to HOST_DIR for libxml, libxslt and libiconv like for
the target variant to avoid a build issue on host where /bin is a
symlink to /usr/bin.
Indeed, the configure script use a custom m4 macro XSTAR_LIB_CHECK to
find xml2-config:
XSTAR_LIB_CHECK([LIBXML], [xml2-config])
This macro come from a local m4 file m4/xstar-check-libs.m4 where it
use:
AC_PATH_PROG(LIBXXX()_CONFIG, xxx_config(),
[], [$LIBXXX()_PREFIX/bin$PATH_SEPARATOR$PATH]
Since no prefix seems to be defined by $LIBXXX()_PREFIX, AC_PATH_PROG
look by itself at /bin/ for xml2-config. So the PATH variable set
by Buildroot containing HOST_DIR/bin is ignored.
The wrong xml2-config is used during the build and the build fail
when no xml2 headers are installed on the host.

[Thomas: remove french messages from the commit log, drop
--with-libiconv-prefix option, since we don't have a libiconv
dependency for the host.]
