With the patch to ld/emultempl/elf32.em I get a new error, which looks 
like the patch itself might be useful (looks like a new library needed 
here?)

collect2: ld returned 1 exit status

(Note the directive "-Wl,-rpath-link,/build/netbsd-local/dest/amd64/lib" ...)

However, the original problem is probably not related to the patch, 
since the ld command explicitly includes "-Wl,-rpath,/lib" (as the very 
first library directives), forcing it to consider the host's libraries 
first.  (Which, in my case are from amd64-6.99.17)

Or am I completely misunderstanding -Wl,-rpath directive?
