Fixes #28456 This commit extends `target_ld_options()` with a NO_SPLIT flag. Specifying `NO_SPLIT` will ensure that all linker flags will be applied together when testing the compiler and linker. This allows a caller to ensure that flags are tested together. This fixes the RISC-V case where the flags `-mabi` and `-march` were omitted because they were tested individually. Note, the update of `target_ld_options()` will allow the same flag on `zephyr_ld_options()` Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>
