and GNU debug information storage. So, we fixed that temporarily (by
changing our filename). However, we found one problem with GNU tools here.
When we do an objdump for this particular option, we find that the
filename(s) are not stored in the executable and hence, the debugger would
not be able to recognize the file. The filename entry(in the auxilliary
symbol) is "fake" instead of the actual filename.

The 'fake' filename is probably a correct one of the assembler source (a
temporary intermediate file). For better filenames try compiling into
assembler sources with the GCC -S switch and then assembling the resulting
source code.
