these symbols are added by assembler, if you have .file asm directive
either explicitly added to .s file or emitted by compiler, compiler
would emit it if the path specified to source file is absolute during
compiler invocation, it will take it verbatim and put it in generated .s
file

you might then want to check if you can see whats happening when this
file is being either compiled or assembled and make the changes there
such that it can be specified via a topdir relative path. that should
fix the issue.
