RISC-V: don't die() on -march errors, just warn

Parsing RISC-V ISA strings is extremely complicated: there are many
extensions, versions of extensions, versions of the ISA string rules,
and a bunch of unwritten rules to deal with all the bugs that fell out
of that complexity.

Rather than die()ing when the ISA string parsing fails, just stop parsing
where we get lost and emit a warning. Changes tend to end up at
the end of the ISA string, so that's probably going to work (and if
it doesn't there's a warning to true and clue folks in).

This does have the oddity in that "-Wsparse-error" is ignored for this
warning but this option was never meant to be used at this stage of
the processing..

[Luc Van Oostenryck: drop handling of "-Wsparse-error"]
