/head per r215840 has working -fvisibility=hidden, i.e. config/gcc_hidden.h.
Try following diff, it should enable patching iconv.h wrapper in bsd.gecko.mk

	@${ECHO_CMD} "#pragma GCC system_header" >> ${MOZSRC}/${subdir}/iconv.h
	@${ECHO_CMD} "#pragma GCC visibility push(default)" >> ${MOZSRC}/${subdir}/iconv.h
	@${ECHO_CMD} "#include \"${LOCALBASE}/include/iconv.h\"" >> ${MOZSRC}/${subdir}/iconv.h
	@${ECHO_CMD} "#pragma GCC visibility pop" >> ${MOZSRC}/${subdir}/iconv.h
