It works for me (on unstable):
olly@gemse:~$ dpkg-buildflags --get LDFLAGS
-Wl,-z,relro
olly@gemse:~$ DEB_LDFLAGS_APPEND=-Wl,--as-needed dpkg-buildflags --get LDFLAGS
-Wl,-z,relro -Wl,--as-needed
Did you include the *export* before them? That's important as it means
make will export the make variable DEB_LDFLAGS_APPEND to an environment
variable with the same name in the environment for child processes.
Without the "export", you've only set the make variable
DEB_LDFLAGS_APPEND, which dpkg-buildflags can't see.
Cheers,
Olly
