riscv: Enable the newfangled way of selecting instruction sets
gcc12+ will require riscv architecture selection to come not only with
featurei suffixd charactersa, it also comes with feature_ful suffix_ed
words_mith. Much creative, very appreciate.
To accommodate for this madness, enable the already existing (but off by
default) support for that in our gcc11 build, support using by detecting
the compiler's behavior in xcompile and pass that knowledge along to our
build system.
Then cross our fingers and hope for the best!
