Initial scripts compatible with Dash (minimalistic POSIX)
Until now, the initial project scripts were primarily tested with GNU Bash. But Bash is not generally available on all systems (it has many features beyond POSIX). Because of this, effectively we were imposing the requirement on the user that they must have Bash installed. We recently started this with setting the shebang of `project' and `reproduce/software/bash/configure.sh' to `/bin/sh'. After doing so, Raul and Gaspar reported an error on their systems. To fix the problem, I installed Dash (a minimalist POSIX-compliant shell) on my computer and temporarily set the shebangs to `/bin/dash', ran the project configuration step and fixed all issues that came up. With this commit, it can go all the way to building GCC on my system's Dash. After this stage (when `high-level.mk' is called), there is no problem, because we have our own version of GNU Bash and that installed version is used. Probably some more issues still remain and will hopefully be found in the future. While doing this, I also noticed the following two minor issues: - The `./project configure' option `--input-dir' was not recognized because it was mistakenly checking `--inputdir'. It has been corrected. - The test C programs now use the `<<EOF' method instead of `echo'. - In `basic.mk', the extra space between `syspath' and `:=' was removed (it was an ancient relic!).
