For what compilation does it fail?

There are three bits/libc-lock.h files:

	sysdeps/generic/bits/libc-lock.h
	sysdeps/mach/bits/libc-lock.h
	linuxthreads/sysdeps/pthread/bits/libc-lock.h

You must be referring to the linuxthreads one, since that's the
only one with BP_SYM & <bp-sym.h>.

The #include is well guarded, and should only happen in the context
where bp-sym.h can be found in sysdeps/generic/bp-sym.h:

------------------------------------------------------------------------------
...

#ifndef __NO_WEAK_PTHREAD_ALIASES
# ifdef weak_extern
#  if _LIBC
#   include <bp-sym.h>
#  else
#   define BP_SYM (sym) sym
#  endif

...
------------------------------------------------------------------------------

How did you get it to fail?  What host & target?
