Because s390 kernel System.map contains symbols that repeat very often
grep -c 'L2^B1$' System.map-2.6.27.7-4-default
276
and the limit for symbols with the same name in get_syment_array() is 200,
we filter out that symbols by modifying s390_verify_symbol() and
s390x_verify_symbol().
The symbols are not needed in crash anyway, because that are only local
labels and not global symbols needed by crash.
This is is a workaround. Andreas Krebbel already worked to resolve the problem
in binutils which prevents that symbols from being included in System.map.
http://sourceware.org/ml/binutils/2009-01/msg00181.html
However, since there are kernels (all 2.6.28 at least) out that contain that
problem, we should also workaround that in crash in my opinion.
