libc/glibc: do not consume parameters when parsing them

Currently, there are two constructs used to parse arguments in
glibc backends, one that consumes args as they are parsed, and
one that does not.

Always use the construct that does not eat args as they are parsed.

     3 	* sysdeps/unix/sysv/linux/alpha/ioperm.c: force the architecture

     4 	  to ev6 in assembly code.

    13 Hrm. gcc puts .arch ev4 into the .s, and this overrides -mev6 for as.

    14 I cannot really think of anything better than
