* elf/dl-open.c (_dl_sysdep_start): Wrap weak_extern decl in BP_SYM ().

Browse Source 
* include/libc-symbols.h (weak_extern): Add extra level of expansion. 
(symbol_version, default_symbol_version): Factor redundant 
definitions out of conditional. 
* linuxthreads/sysdeps/pthread/bits/libc-lock.h: 
Wrap BP_SYM () around weak extern declarations of pthread 
functions that have pointers in their return+arg signatures.
