    depend-cleanup.sh: Clean up after riscv static binary IFUNC addition
    
    reloc.c is conditionally included by libc_start1.c so existing builds
    don't feature it in the .depend file and won't know they need to rebuild
    libc_start1.c.
    
    MFC after:      1 week
    
    (cherry picked from commit d41a40f484826e90ed78dce5f006712b0eeaf501)
