Sorry about this, I published a new version of the stm32f30x crate without making adequate preparations and testing, but the problem should now be fixed.
To get the fix you'll have to update some crates in your dependency graph by either deleting the Cargo.lock file or calling cargo update.
Let me know if this still doesn't work after you have tried that!

Thank you Sir.
The problem is fixed now.
In another note.
Is the use of target -> ../../target/ safe with cargo ?
I understand it is used to reduce compiling time,
but if I cargo build in 05-led-roulette
and then in 06-hello-world,
and then again in 05-led-roulette,
only the first build will success.
something like the following will happen :
/home/xyh/magismoke/discovery/src/06-hello-world (master)
cargo build
Compiling vcell v0.1.0
Compiling aligned v0.2.0
Compiling r0 v0.2.2
Compiling bare-metal v0.2.3
Compiling nb v0.1.1
Compiling void v1.0.2
Compiling cast v0.2.2
Compiling cortex-m v0.5.7
Compiling typenum v1.10.0
Compiling cortex-m-rt v0.6.2
Compiling stm32f30x v0.7.1
Compiling volatile-register v0.2.0
Compiling embedded-hal v0.2.1
Compiling f3 v0.6.1
Compiling cortex-m-rt v0.5.7
Compiling generic-array v0.11.1
Compiling lsm303dlhc v0.2.0
Compiling l3gd20 v0.2.0
Compiling stm32f30x-hal v0.2.0
Compiling aux6 v0.1.0 (file:///home/xyh/magismoke/discovery/src/06-hello-world/auxiliary)

and
/home/xyh/magismoke/discovery/src/05-led-roulette (master)

and the Cargo.lock file follows this target -> ../../target/ to ../../Cargo.lock

Is the use of target -> ../../target/ safe with cargo ?
That's just a convenience and has no effect on the build. All the projects are part of a workspace so they share their build artifacts in the target directory that's in the root of the repository.
but if I cargo build in 05-led-roulette
If you read through the book in order it'll tell that you have to use cargo build --target thumbv7em-none-eabihf in projects 05 and 06. You can use just cargo build in the other projects because thumbv7em-none-eabihf has been set as default compilation target in .cargo/config.
$ cd 05-led-roulette
$ cargo clean
$ cargo build --target thumbv7em-none-eabihf && echo OK
Finished dev [unoptimized + debuginfo] target(s) in 38.91s
OK
$ cd ../06-hello-world
$ cargo build --target thumbv7em-none-eabihf && echo OK
Finished dev [unoptimized + debuginfo] target(s) in 0.30s
OKfrom discovery.
