This allows cargo to use make's jobserver when building packages, by
marking the cargo command as recursive (with the + prefix[1]) and
setting MAKEFLAGS.
This also:
* Give cargo/x.py the build directory instead of having to change the
current directory (and opening subshells)
* Set PKG_BUILD_PARALLEL/HOST_BUILD_PARALLEL for Rust packages to enable
the use of make's jobserver

This consolidates all environment variables for cargo into:
* CARGO_HOST_CONFIG_VARS / CARGO_PKG_CONFIG_VARS
These contain all cargo-specific environment variables, i.e. without
"common" variables like CC.
* CARGO_HOST_VARS / CARGO_PKG_VARS (renamed from CARGO_VARS)
These contain all environment variables to be passed to cargo.
This also:
* Set the CARGO_BUILD_TARGET environment variable instead of using the
--target command-line option
* Update Python include files to use CARGO_HOST_CONFIG_VARS /
CARGO_PKG_CONFIG_VARS

This also:
* Modify the "release" profile in place of adding the "stripped" profile
Only the profile for target is modified; there are no file size
constraints for host.
* For host, build with the "release" profile
* For target, build with either the "dev" or "release" profile based on
CONFIG_DEBUG
There is no environment variable to specify the "strip" option, but
enabling this option is not necessary as the build system will already
strip binaries based on CONFIG_NO_STRIP / CONFIG_USE_STRIP /
CONFIG_USE_SSTRIP.

This allows rustc/cargo/etc to be called without having to set PATH, as
$(STAGING_DIR)/host/bin is already in PATH.
This also fixes CARGO_HOME not being set during Host/Configure and
Host/Compile.

Added new RUST_PKG_FEATURES flag.
Moved CARGO_HOME to STAGING_DIR_HOSTPKG.
Overrode default Build/Compile and Host/Compile to Cargo build.
