    Don't assert at ldwrite.c:212
    
    When excluding SHF_LINK_ORDER sections that happen to have SEC_KEEP
    set, we need to set SEC_EXCLUDE here to avoid a problem later.
    
            * ldelf.c (ldelf_before_place_orphans): Set SEC_EXCLUDE for
            discarded sections.
    
    (cherry picked from commit 5987401fcbc9933808fa0d84d1b01c93356c39a1)
