Steven Walter 48e2a7db25 cargo_common.bbclass: improve operation with devtool
Because devtool inhibits all the normal bitbake fetchers, we can't mask crates.io.
Use EXTERNALSRC to detect if we're being built with devtool, and only mask
crates.io if we're not.

Fixes #195

##
## Purpose:
## This class is to support building with cargo. It
## must be different than cargo.bbclass because Rust
## now builds with Cargo but cannot use cargo.bbclass
## due to dependencies and assumptions in cargo.bbclass
## that Rust & Cargo are already installed. So this
## is used by cargo.bbclass and Rust
##
# add crate fetch support
inherit crate-fetch
inherit rust-common
# Where we download our registry and dependencies to
export CARGO_HOME = "${WORKDIR}/cargo_home"
# The pkg-config-rs library used by cargo build scripts disables itself when
# cross compiling unless this is defined. We set up pkg-config appropriately
# for cross compilation, so tell it we know better than it.
