 GCC has since at least version 6 the following option (-ffile-prefix-map
 since version 8):

 https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html#index-fdebug-
 prefix-map

 This way we can install the Newlib (and maybe libgcc, libgomp, libatomic,
 libstdc++ sources) through the RSB in a prefix location and direct the
 debugging information to this install location.
