[build] Use -Wno-decl when running sparse 

Linker table entries must be non-static in order to avoid being
completely optimised away by some versions of gcc.  Use -Wno-decl to
prevent sparse from warning about these, since the alternative would
be to litter the code with otherwise unnecessary "extern"
declarations.
