Thanks for pushing me to look at other solutions.
After poking some more at GCC and its documentation, I came up with the
attached patch. It only adds two new switches to the CFLAGS:
`-fdebug-prefix-map=` to adjust the source path and
`-gno-record-gcc-switches` to prevent the difference in
`-fdebug-prefix-map=` values from affecting the output.
Does that sound more acceptable to you?
