RISC-V: Match GCC's semantics for multiple -march instances
GCC's semantics for "-march=X -march=Y" are that Y entirely overrides X,
but sparse takes the union of these two ISA strings. This fixes the
behavior by setting, instead of oring, the flags whenever a base ISA is
encountered. RISC-V ISA strings can only have a single base ISA, it's
not like x86 where the 64-bit ISA is an extension of the 32-bit ISA.
[Luc Van Oostenryck: reset the flags at the start of the parsing loop]
