Makefile: fix warnings when linking with clang++

Clang ignores some options during linkage and warns about it:

  clang: warning: argument unused during compilation: '-ansi'
  clang: warning: argument unused during compilation: '-Wp,-D_FORTIFY_SOURCE=2'

Add -Qunused-arguments to LDFLAGS to suppress the warnings.
