Rust is not passing the sysroot flag to Clang when invoking it as the
linker. This means files from the host may leak in, and host targets
may fail if sysroot files are not available from the host.
This patch prepends the lld flags from cc into rust linkargs. This
pulls in the sysroots flag, and also ensures that we remain in sync
with linkage flags used in cc.
The '-Wl,--no-undefined-version' from cc is overridden to avoid
missing version assignment errors for rust's generated alloc
functions.

Test: cd external/rust; mma
Test: strace -f -e %file <host libstd.dylib.so build command> pulls
from correct sysroots.

Now that we have sysroots built in Soong, we can enable these devices
and they just work.

Adds support to Soong for building rust modules. This currently only
supports x86_64 device and x86 linux host targets. The functionality
is sufficient to build crosvm.
