433:_RELRO_LDFLAGS=             -Wl,-zrelro -Wl,-znow
435:_RELRO_LDFLAGS=             -Wl,-zrelro

61:_RELRO_LDFLAGS=              -Wl,-zrelro -Wl,-znow
63:_RELRO_LDFLAGS=              -Wl,-zrelro

and the above works:
# make show-var VARNAME=LDFLAGS
  -Wl,-zrelro -Wl,-znow

Well, the relro arguments from above are missing.
