However, it relies on initializations made in `PLATFORM_SETUP_OPENJDK_BUILD_AND_TARGET` and `BASIC_SETUP_PATHS`. Currently, `UTIL_LOOKUP_PROGS(GIT, git)` is called too early in configure and hence the problematic Windows path is not handled correctly. My fix makes sure that only the barely necessary tool lookups required for `PLATFORM_SETUP_OPENJDK_BUILD_AND_TARGET` and `BASIC_SETUP_PATHS` are made in `BASIC_SETUP_FUNDAMENTAL_TOOLS` and everything else is moved into another macro called `BASIC_SETUP_TOOLS` that is invoked after path handling is set up correctly, which includes the lookup of git.
