1. Use suffixes such as _class-native, _class-target, etc.
I think this is the preferred way.
Please grep the repo for more info.

2. Use ${PN} value.
e.g. (from dpkg.inc)
do_install_append () {
         if [ "${PN}" = "dpkg-native" ]; then
                 # update-alternatives doesn't have an offline mode
                 rm ${D}${bindir}/update-alternatives
                 sed -i -e 
's|^#!.*${bindir}/perl-native.*/perl|#!/usr/bin/env nativeperl|' 
${D}${bindir}/dpkg-*
         else
                 mv ${D}${bindir}/update-alternatives ${D}${sbindir}
                 sed -i -e 
's|^#!.*${bindir}/perl-native.*/perl|#!/usr/bin/env perl|' 
${D}${bindir}/dpkg-*
         fi
}
