Mega-commit removing deps in xbps-base-chroot.

xbps-src:
  * ALWAYS use the static bins, to avoid breakage in the chroot.
  * Remove XBPS_FETCH_CMD. Use xbps-fetch (static) now that it's
    useful to download all distfiles in xbps-base-system.
  * Use busybox in the chroot and create links in /usr/local/bin
    at creation time. This helps to remove many packages that
    had problems with host/target libs (acl, attr, libarchive, etc).

build templates:
  * Add explicit gettext and texinfo build dependencies in all
    packages that need them, because they aren't built anymore
    by xbps-base-chroot.
  * Fixed some packages using build_style=gnu_makefile, that were
    broken because pre/post_configure() is not executed for a while,
    they should use pre/post_build() instead.
