cc/gcc: CC_STATIC_LIBSTDCXX 'depends on' CONFIGURE_has_static_libstdcpp

Hide the staticaly linked libstdc++ option if the static libstdc++ is not
present, detected at configure time.

Add a blind option that says whether static linking is possible at all.
It defaults to 'y', but depends on the needed CONFIGURE_* options. For
now, it only depends on static libtdc++, but new dependencies can be
easily added.

Hide the global static toolchain option behind this new option.

    33       The newlib "team" rolls new releases about once a year (december).

    34       This is quite a long time between releases, in case code was fixed.

    35       

    36       Saying 'Y' here will allow you to use the bleeding-edge code from

    37       the CVS repository. This may or may not fix your issues, may or may

    38       not build, may or may not crash your machine, may or may not withdraw

    39       money from your bank account, may or may not date your girlfriend,

    40       may or may not resurect Elvis... :-)

    41       

    42       In a word: use the CVS snapshot at your own risk!
