That's because this is a 'blind' options that is selected because other
options need it. For example:

config/cc/gcc.in.2:
  43  config CC_STATIC_LIBSTDCXX
  44      bool
  45      prompt "Link libstdc++ statically into the gcc binary"
  46      default y
  47      depends on CC_GCC_4_4_or_later
  48      select WANTS_STATIC_LINK

So, if you sleected to statically link libstdc++, CT_WANTS_STATIC_LINK
*will* be selected.

Editing the .config file by hand is *NOT* the solution. Better understand
*why* you can't link statically on openSuSE.

Please, see the code that does the failing test, run it by hand, note the
error you get, and try to see how the code could be changed so as to avoid
this error.
