if I remember right (did not check the sources recently), -append is used to 
add args to the kernel, a mechanism that always passes the long kernel absolute 
path as argv[0].

for semihosting cases the command line has a different purpose, and must not 
hardwire argv[0] to the kernel path.

in my use case I actually do not use -kernel/-append at all, I load the image 
via the gdb server, as for any existing bare metal board. passing semihosting 
options via -semihosting-config is the natural solution.

I think that configuring the kernel and configuring semihosting are two 
different things, and should have different command line options.
