Unrecognized option '-Wl,--mgen-symbol-ld-script=export.txt'

Hello,I try to add a script '-Wl,--mgen-symbol-ld-script=export.txt' in "optins for target"/"linker"/"misc controls". After build, when linking it shows

error: L3900U: Unrecognized option '-Wl,--mgen-symbol-ld-script=export.txt'.

Any idea how to fix this error?
