May I suggest using a help function to simplify the code a lot:

copy_locale_files() {
	local dir=$1 mode=$2

	[ -e "${LOCALETREESRC}$dir" ] || return 0

	for d in . $(find "${LOCALETREESRC}$dir" -type d -printf '%P '); do
		install -d ${D}$dir/$d
		find "${LOCALETREESRC}$dir/$d" -maxdepth 1 -type f \
		     -exec install -m $mode -t "${D}$dir/$d" {} \;
	done
}

do_install() {
	copy_locale_files ${bindir} 0755
	copy_locale_files ${localedir} 0644
	if [ ${PACKAGE_NO_GCONV} -eq 0 ]; then
		copy_locale_files ${libdir}/gconv 0755
		copy_locale_files ${datadir}/i18n 0644
	fi
	copy_locale_files ${datadir}/locale 0644
	install -m 0644 ${LOCALETREESRC}/SUPPORTED ${WORKDIR}/SUPPORTED
}

The code above is untested, but I think I got it reasonably correct. 
Also note that I have restored the indentation to use tabs, and 
turned the access to the ${PACKAGE_NO_GCONV} variable into a 
simple variable instead of using d.getVar().
