ruby: explicitly disable SSP support

The SSP support checks of the Ruby configure script do not do a full
link, and therefore don't properly detect if SSP support is fully
functional or not, which causes some build failures if the compiler
supports -fstack-protector but the C library does not provide the SSP
implementation.

To avoid this, we explicitly tell ruby if SSP support is available or
not.
