Got a very quick and polite response from Ian Wienand, confirming that
LD_PRELOAD does indeed go at the front of the list, and that the first
occurrence is preferred.

He offered this link to the source for details:
http://repo.or.cz/w/glibc.git/blob/HEAD:/elf/rtld.c#l1696

His response did make me wonder about another question:  are we
concerned with loading extensions at runtime (after startup) through
dlopen() type mechanisms, or do we expect all extensions to be
available at compile time?
