In Makefiles, variables are split, filtered, and otherwise mangled on a space as a separator. In a shell, they will also be split on TABs. We split and filter and iterate on variables in a lot of places, and most importantly, spaces in PATH is very seldom tested, if at all, so a lot of packages will not be working properly in such a situation. For example, the config.guess contains constructs that are not resilient to a space in PATH: PATH=$PATH:/.attbin ; export PATH Also, our fakedate will iterate over PATH: for P in `echo $PATH | tr ':' ' '`; do Those are only two cases, but the first means basically all autotools-based packages are susceptible to subtle breakage. Furthermore, Buildroot itself does not support that the top-level or output directories are in a path with spaces anyway. So, instead of chasing all cases that might be potentially broken, let's just detect the case and bail out, like we already do when PATH contains a \n, or when it contains the current working directory.
