Building sysutils/opensbi with clang 17 results in the following errors: clang: error: unsupported option '-mno-unaligned-access' for target 'riscv64-unknown-elf' clang: error: unsupported option '-mno-unaligned-access' for target 'riscv64-unknown-elf' [... many more times...] The target-specific option -mno-unaligned-access (which is emitted from the compiler driver when -mstrict-align is used) did not do anything for riscv64, but clang 17 is now more strict about reporting unsupported options. Remove the -mstrict-align option from the Makefile's CFLAGS and ASFLAGS to fix it. PR: 273753 MFH: 2023Q4
