resources: Update m5 command to cross compile
By default, the cross compiler used by scons to compile riscv targets
is riscv64-unknown-linux-gnu-, which is the one used throughout this
README file. However, it's important to point out how to change
the cross compiler as it's very likely to be varied from a system
to another.

+**Note**: the default cross-compiler is `riscv64-unknown-linux-gnu-`. To change the cross-compiler, you can set the cross-compiler using the scons sticky variable `riscv.CROSS_COMPILE`. For example,
+```sh
+scons riscv.CROSS_COMPILE=riscv64-linux-gnu- build/riscv/out/m5
+```
