Then use symlinks.
What search path does ld.so with your patch use with say
LD_LIBRARY_PATH=/usr/lib (LD_DEBUG=all will write it in the beginning)?
On i686, the search path is already too long:
search path=/usr/lib/tls/i686/mmx:/usr/lib/tls/i686:/usr/lib/tls/mmx:/usr/lib/tls:/usr/lib/i686/mmx:/usr/lib/i686:/usr/lib/mmx:/usr/lib

Except for the runtime cost...
