These five lines are not necessary.

The subprojects also need to be added to scripts/archive-source.sh and 
scripts/make-release.

In order to simplify a future switch to Cargo projects, this should be 
something like:

subproject('bilge-0.2-rs', required: true)
subproject('bilge-impl-0.2-rs', required: true)

bilge_dep = dependency('bilge-0.2-rs')
bilge_impl_dep = dependency('bilge-impl-0.2-rs')

with a corresponding

meson.override_dependency('bilge-0.2-rs', bilge_dep)

in subprojects/packagefiles/bilge-0.2-rs/meson.build.

Also in bilge's meson.build:

native should not be true here (but it should be true for the 
dependencies of bilge-impl: either, itertools, proc-macro-error, 
proc-macro-error-attr, proc-macro2, quote, syn, unicode-ident).

I've placed my updates at a branch "rust-for-manos" of 
https://gitlab.com/bonzini/qemu/.  I left the fixes unsquashed for your 
review, but feel free to merge them and post the result as part of v7.
