BinaryBuilder has a very nice cross-platform toolchain, but if I want to use it to build locally for execution, i.e. ship source code and a build script because this is more flexible, in which case building for platforms other than the current one is pointless, how can I auto-detect current platform and only build for it?

`HostPlatform()` is your current platform:

```julia
julia> HostPlatform()
Linux x86_64 {cxxstring_abi=cxx11, julia_version=1.6.4, libc=glibc, libgfortran_version=4.0.0, libstdcxx_version=3.4.29}

```

so you can have

```julia
platforms = [
    HostPlatform()
]

```

but please do note that it contains some extra ABI specifications (like C++ string ABI and libgfortran version) that may be overly restrictive, in case you want to publish a JLL package.
