This change causes problems:
'make -j4 buildworld' fails, seemingly random, eg. as below.
this is with /usr/src and /usr/obj nfs mounted; nfs server running dfly 1.8.2.

After make failed, executing 'mv _clear_cache.o.tmp _clear_cache.o' succeded.

 - vfs.nfs.pos_cache_timeout=0 doesn't help.
 - 'make -j1 buildworld' succeeds.
 - using ufs for /usr/obj makes -j4 work.
 - backing change in commit out (and using nfs for /usr/obj) makes -j4 work.

- 'make -j4 buildworld' with /usr/obj nfs mounted
