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 the R10000 needs an LL/SC Workaround. If not applied all R10k before

     4 rev 3.0 misbehave on atomic ops and rev 2.6 and lower (e.g. SGI IP28)

     5 die after very few seconds with a deadlock due to even more erratas.
