Make compiler flags for reproducible builds optional

no change in default behavior: -ffile-prefix-map is still added if
supported by compiler but add option for disabling it as it breaks
generic tools for extracting debuginfo/debugsource from build artifacts
like: https://sourceware.org/git/?p=debugedit.git;a=blob;f=scripts/find-debuginfo.in
