Merge #20353: configure: Support -fdebug-prefix-map and -fmacro-prefix-map
7abac98d3e3c1bc8ad66cb5c05184b9c5cc674d5 configure: Support -f{debug,macro}-prefix-map (Anthony Towns)
Pull request description:
When bitcoin is checked out in two directories (eg via git worktree) object files between the two will differ due to the full path being included in the debug section. `-fdebug-prefix-map` is used to replace this with "." to avoid this unnecessary difference and allow ccache to share objects between worktrees (provided the source and compile options are the same).
Also provide `-fmacro-prefix-map` if supported so that the working dir is not encoded in `__FILE__` macros.
