All the better.
One more question about this macro: What is the difference between
-Xlinker and -Wl (apart from the slightly different syntax)? libtool and
config.rpath sometimes use -Wl to pass an option to the linker and never
-Xlinker, whereas your macro uses sometimes -Xlinker and never -Wl.
It appears that -Xlinker is supported only by gcc, and -Wl by other
compilers too?

The variables were not meant to be used with eval, just to be used
without quotes, like this:
$LDDPROG program $LDDPOSTPROC
Which problem did you run into?
