Yeah, I got that all these prefixes are not working with modified

That's also a solved problem in nvptx mkoffload - you do need to unset these
environment variables when invoking the target compiler. I've posted the
source a few times but here it is again.


I see there:
   unsetenv ("GCC_EXEC_PREFIX");
   unsetenv ("COMPILER_PATH");
   unsetenv ("LIBRARY_PATH");

Or do you mean, that there is no need to set them to the new values
before invoking the target compiler?
Exactly - you need to unset them before calling x86-accel-nvptx-gcc, but that driver has its own logic to find its binaries, so nothing else is necessary. You need to know where to find x86-accel-nvptx-gcc, and that can be done by examining COMPILER_PATH.
