OpenBSD/src ImkLqcSlibexec/ld.so resolve.c loader.c

   In 2004, we upgraded to binutils 2.14 with did -zcombreloc by default.
   In 2013, I implemented the single-entry LRU cache that gets the maximal
   symbol reuse from combreloc.  Since then, the ld.so generic relocation
   symcache has been a waste of CPU and memory with 0% hit-rate, so kill it.
