make export writes several names into LDNAME for boards that use more than one linker script. The exported toolchain.cmake only prefixed the first file, so ld searched for the rest in the application build directory. Normalize NUTTX_PATH so the generated -T arguments do not keep the scripts/../scripts form. Fixes apache/nuttx#19820. Signed-off-by: Zhaoqi Xu <lzy00419@outlook.com>
