    PR ld/24709 [arm] linker crash and assertion failure with CMSE

    As discussed in the PR, we do not support the case where CMSE stubs
    are inserted too far from their destination. This would require an
    intermediate long-branch stub, which is tricky in this context.

    Instead of crashing, this patch emit an error message and exits.

        * bfd/elf32-arm.c (CMSE_STUB_NAME): New define.
        (elf32_arm_get_stub_entry): Do not try to emit long-branch stubs
        for CMSE stubs.
        (arm_dedicated_stub_output_section_name): Use CMSE_STUB_NAME.
