The RISC-V GCC port now specifies the default code model (cmodel) directly within OPTION_DEFAULT_SPECS. While TARGET_DEFAULT_CMODEL generally sets the default, this explicit specification is necessary to correctly handle multilib configurations. This ensures that the compiler accurately detects and applies the appropriate code model for different multilib targets, improving the reliability of RISC-V binaries built with GCC.
