arch/riscv: Adjust compiler flags for scan-build

Clang doesn't understand -march=riscv64imac and -mcmodel=medany, so
don't use them when running the clang static analyzer. On the other
hand, __riscv and __riscv_xlen need to be defined in order to select
some macros in src/arch/riscv/include/arch/encoding.h. -mabi is moved
-march for consistency.

With this commit, scan-build produces a useful result on RISC-V.
