Single wrapper instead of old ./configure, Makefile and ./for-group
Until now, to work on a project, it was necessary to `./configure' it and build the software. Then we had to run `.local/bin/make' to run the project and do the analysis every time. If the project was a shared project between many users on a large server, it was necessary to call the `./for-group' script. This way of managing the project had a major problem: since the user directly called the lower-level `./configure' or `.local/bin/make' it was not possible to provide high-level control (for example limiting the environment variables). This was especially noticed recently with a bug that was related to environment variables (bug #56682). With this commit, this problem is solved using a single script called `project' in the top directory. To configure and build the project, users can now run these commands: $ ./project configure $ ./project make To work on the project with other users in a group these commands can be used: $ ./project configure --group=GROUPNAME $ ./project make --group=GROUPNAME The old options to both configure and make the project are still valid. Run `./project --help' to see a list. For example: $ ./project configure -e --host-cc $ ./project make -j8 The old `configure' script has been moved to `reproduce/software/bash/configure.sh' and is called by the new `./project' script. The `./project' script now just manages the options, then passes control to the `configure.sh' script. For the "make" step, it also reads the options, then calls Make. So in the lower-level nothing has changed. Only the `./project' script is now the single/direct user interface of the project. On a parallel note: as part of bug #56682, we also found out that on some macOS systems, the `DYLD_LIBRARY_PATH' environment variable has to be set to blank. This is no problem because RPATH is automatically set in macOS and the executables and libraries contain the absolute address of the libraries they should link with. But having `DYLD_LIBRARY_PATH' can conflict with some low-level system libraries and cause very hard to debug linking errors (like that reported in the bug report). This fixes bug #56682.
