It isn't needed, and in some configurations it causes build failures.
Similar problems could still occur for other file types with a similar
vpath, but it's less likely that other file types would be installed in
an equivalent $(TOP)/../<dir> path.
The original issue with .pl files was caused by an installation of Base
where the parent directory had a bin/<host> soft-link pointing to the
same bin/<host> of a newer installation of the same version of Base, so
it had all the necessary .pl files in it. The vpath allowed the build in
src/tools to search $(TOP)/../bin/<host> when checking the buildInstall
dependency, and since it found those .pl files through the vpath it
didn't bother to install them. When they were run later on in the build
from the $(TOP)/bin/<host>/ path they weren't present so it failed.
