Description
CROSS_COMPILE=riscv64-elf- make -C build/opensbi PLATFORM=generic FW_TEXT_START=0x40000000 FW_OPTIONS=0
ELF platform/generic/firmware/payloads/test.elf
/usr/lib/gcc/riscv64-elf/12.2.0/../../../../riscv64-elf/bin/ld.bfd: unrecognized option '--exclude-libs'
/usr/lib/gcc/riscv64-elf/12.2.0/../../../../riscv64-elf/bin/ld.bfd: use the --help option for usage information
collect2: error: ld returned 1 exit status
Is this because the toolchain is for bare-metal?
Should the toolchain be checked before --exclude-libs is added to ELFFLAGS?

Research direction
Reproduce the failure with the reported CROSS_COMPILE and make command, then trace where --exclude-libs is added to ELFFLAGS. Check how the bare-metal linker handles that option and verify the build succeeds or the unsupported-toolchain behavior is clearly handled.
