It's possible to declare these types if you need to use them.

    [CCode (has_type_id = false)]
    [FloatingType (decimal = false, rank = 12, width = 128]
    struct float128_t {}

Good idea! Probably better still:
[SimpleType]
[CCode (has_type_id = false)]
[FloatingType (decimal = false, rank = 12, width = 128]
public struct float128_t {}
I think the SimpleType tells Vala the usual struct syntax isn't needed.You may also need the cheader_filename 
in there as welll.
You could also play around with the name, e.g. use cname="float128_t"then call it:public struct float128 
{}but maybe that should wait to see if it becomes bound in GLib first.
As an example, this is how double is bound to
