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.

     7 	used later with MMAP_FIXED | MMAP_SHARED to cope with different

     8 	alignment restrictions.
