json-spirit: link to libatomic

In commit ac2a6d2b5d69937577effcb8bb2149651bac0176:
[ json-spirit: Add -latomic to LDFLAGS ]

I added '-latomic' to LDFLAGS, which worked for clang 3.9 but it does
not work for clang 5.0, seems the linking order matters for clang 5.0,
it should be after -ljson_spirit.
