Why force linking compression library through LDFLAGS?

[Yumin Xia]

gorocksdb/dynflag.go

Line 5 in 1625521

 // #cgo LDFLAGS: -lrocksdb -lstdc++ -lm -lz -lbz2 -lsnappy -ldl 

gorocksdb/staticflag_linux.go

Line 5 in 1625521

 // #cgo LDFLAGS: -l:librocksdb.a -l:libstdc++.a -l:libz.a -l:libbz2.a -l:libsnappy.a -lm 

If rocksdb is compiled without the above compression library, link will fail.
