    RISC-V: Add target machine headers as a dependency for riscv-sr.o
    
    Make riscv-sr.o depend on target machine headers, removing spurious test
    failures:
    
    FAIL: gcc.target/riscv/save-restore-3.c scan-assembler-not call[ \t]*t0,__riscv_save_0
    FAIL: gcc.target/riscv/save-restore-3.c scan-assembler-not tail[ \t]*__riscv_restore_0
    FAIL: gcc.target/riscv/save-restore-3.c scan-assembler tail[ \t]*foo
    FAIL: gcc.target/riscv/save-restore-6.c scan-assembler-not call[ \t]*t0,__riscv_save_0
    FAIL: gcc.target/riscv/save-restore-6.c scan-assembler-not tail[ \t]*__riscv_restore_0
    FAIL: gcc.target/riscv/save-restore-6.c scan-assembler tail[ \t]*other_func
    
    if the definitions of UNSPECs are locally changed and GCC rebuilt from a
    dirty tree.

            * config/riscv/t-riscv (riscv-sr.o): Add $(TM_H) dependency.
