Greg McGary c62f5cab71 * include/libc-symbols.h [!__ASSEMBLER__] (strong_alias):
Add extra level of macro expansion. 
[!__ASSEMBLER__ && HAVE_WEAK_SYMBOLS] (weak_alias): nLikewise. 
* sysdeps/generic/bp-thunks.h: Ensure `struct timeval' definition 
is available at the time `select' prototype is declared. 
* sysdeps/unix/make-syscalls.sh: Remove unused variables. 
Collect non-versioned weak aliases.  Consider only non-versioned 
aliases for the user-visible systemcall name.  Do checks inline with 
call to primitive system call. 
* sysdeps/unix/sysv/linux/ptrace.c (ptrace): Add void cast to 
stand-alone bounds checks to suppress unused value warnings. 
* sysdeps/unix/sysv/linux/sysctl.c (__sysctl): Likewise.
