[Bug other/37210] Prohibit Default Builds in the GCC Source Tree

Andrew, you're right--it's not prohibited, but my argument is that it should be
prohibited as the default build (but have a specific configure variable to
allow it), at least until it is tested.  Over the years I've watched people
have a build  problem, and the first thing the gurus tell them is *don't* build
in the gcc tree, so this enhancement would at least get newbies' attention
instead of continuing to waste help bandwidth.  Note the recommendation to not
build in the tree has been around I'll guess for at least ten years.  And with
the complexity of the build I doubt that the tested in-tree build will ever be
a requirement for a release.

I envision a short but succinct message telling about the prohibition and
adding a link to more detail.  The installation instructions should perhaps
have text enhancement or other edits to highlight the reason for the
prohibition.
