    editors/libreoffice: fix build with lld 17 (take 2)
    
    Building editors/libreoffice with lld 17 results in the following link
    errors:
    
      ld: error: version script assignment of 'PRIVATE_1.4' to symbol '_ZN3sal13backtrace_getEm' failed: symbol not defined
      ld: error: version script assignment of 'GLIBCXX_3.4' to symbol '_ZNSs4_Rep20_S_empty_rep_storageE' failed: symbol not defined
    
    Add -Wl,--undefined-version to LDFLAGS to suppress these error, as the
    previous fix did not work in all cases.
