Commit 43025f0 ("RISC-V: Improve link time complexity.") reduced the time complexity of the linker relaxation but some code portions did not reflect this change. This commit fixes a comment describing each relaxation pass and reduces actual number of passes for the RISC-V linker relaxation from 3 to 2. Though it does not change the functionality, it marginally improves the performance while linking large programs (with many relocations). bfd/ChangeLog: * elfnn-riscv.c (_bfd_riscv_relax_section): Fix a comment to reflect current roles of each relaxation pass. ld/ChangeLog: * emultempl/riscvelf.em: Reduce the number of linker relaxation passes from 3 to 2.
