For those who are curious, too, I'll quote the paragraph:

"[...] Because dlopen/dlsym is a rather inconvenient system to use, we 
produced relaytool, which allows a "soft link" against software with no code 
changes beyond a simple if (libfoo_is_present) { ... } conditional. There is 
no need to define lots of function pointers, it works for C++ and it supports 
exported variables. If linking to libraries at runtime does not look elegant 
because of the ugliness of the resulting code, relaytool is exactly what is 
needed."

This link is given, which allows to download the shell-script "relaytool":
http://cvs.sunsite.dk/viewcvs.cgi/*checkout*/autopackage/apbuild/relaytool

Its header contains some usage details, and the TODO "port to more archs".  
Looks cool though. :-)
