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.
