When building a cross-compiler ld for RISC-V Linux systems, you can specify target=riscv64*-linux* to create a linker that supports both 32-bit (-march=rv32*) and 64-bit (-march=rv64*) architectures. The specified -march value populates the EMULATION_NAME variable, which determines the default linker script selection. For proper riscv64 target support, the build process must prepare both elf32lriscv* and elf64lriscv* linker scripts. These should align with the standard RISC-V Linux sysroot directory structure.
