Problems with build.jl from BinaryBuilder

[lobingera]

I'm trying to integrate from here
https://github.com/lobingera/Cairo.jl/blob/bb2/deps/build.jl
and get longer list of

julia> BinaryProvider.locate(products[1],verbose=true,isolate=true)

although,

build.jl was borrowed from
https://github.com/giordano/Yggdrasil/releases/download/Cairo-v1.14.12/build_Cairo.v1.14.12.jl

@giordano investigated this and discovered that it was due to an implicit ordering between libraries; if libA depends on libB, then including the build.jl for libB before that of libA would cause libB to not be dlopen'able, which would manifest in problems like above. By permuting the ordering of build.jl files being included, he fixed the issues.

This will be fixed for Julia 1.3+ as we are able to take advantage of the Artifacts and JLL package systems, which will impose an implicit ordering upon library open order.

@staticfloat I see - can you please document this?
