wrong command suggestion on precompile error

[Ken-B]

When loading SpecialFunctions failed, it should suggest to re-run Pkg.build("SpecialFunctions") instead of re-run Pkg.build("fvheQ") (the latter command does not work).

At JuliaLang/Pkg.jl#1290 it was suggested this might be an issue of BinaryProvider.jl.
