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.
