Also, the meaning of "LDFLAGS" is ambigous, which means implicitly 
passing it is somewhat dangerous.

It may mean flags to be passed to the linker through the compiler", but 
there also exist Makefiles/build environment, which treat LDFLAGS as 
"flags to be directly passed to the linker".

-Wl,-z,relo is from the former family (-Wl ... gcc options to be passed 
to the linker through gcc).

gmake defines it as (from "info make"):

`LDFLAGS'
      Extra flags to give to compilers when they are supposed to invoke
      the linker, `ld'.
