RISC-V: Set EF_RISCV_TSO also on .option arch
This is a minor fix to commit 96462b012988d35ebb1137a2ad9fd0a96547d79a ("RISC-V: Implement Ztso extension"). Currently, it sets EF_RISCV_TSO ELF flag when initial ISA string contains the 'Ztso' extension. However, GAS has a way to update the ISA string: ".option arch". When the architecture is updated by ".option arch", EF_RISCV_RVC ELF flag is set when the 'C' extension is detected. Analogously, this commit sets the EF_RISCV_TSO when the 'Ztso' extension is detected. gas/ChangeLog: * config/tc-riscv.c (s_riscv_option): Set TSO ELF flag if the 'Ztso' extension is specified via ".option arch" directive.
