xray: conditionally forward compiler/linker flags to enable xray profiling
...
You have to set the variable PROFILING to something to enable profiling using
Xray. In order for profiling code to be compiled into the runtime and demo
applications you must clean the whole project before.
Example:
$ cd HermitCore
$ make clean
$ make PROFILING=yes
Hint: You can also export the variable (`export PROFILING=yes`) for a more
permanent configuration.

Makefile: start Qemu with GDB enabled by default
...
The serial terminal is now at port 1235 since it clashes with the port GDB
is trying to bind to. So GDB:1234 and Serial:1235
