"mcount" (or the name we specify here) is the function called by compiler generated instrumentation code when profiling is enabled.

VxWorks would need to implement this function (we don't currently have it). Removing this code doesn't actually disable calls to mcount, it just reverts to the default name "mcount".
For clarity I suggest adding a line to vxworks_base.rs:
target_mcount: "_mcount".to_string(), // VxWorks needs to implement this to support profiling

Move the following common settings from the target specific files to vxworks_base.rs:
- target_os
- target_vendor
- linker_flavor

Done. I also moved target_env to vxworks_base as they are all "gnu".

Actually I need to revert the change here. The vxworks_base.rs suppose to hold all "options", but
they doesn't belong to "options".

What is vx-run (or wr-run)?

This is the script I used to run test case on board(Simics, Vxsim or real board).
