It is standard GNU Make behaviour to stop at the first build
failure. If you want to build and run all the tests use 
`make -k` instead.

Please note that you should not install the built glibc until you 
understand the cause of the failures for your particular 
environment.

That's also expected. Running `make check` will not re-run a
test case you have already run. To re-run all of the test you
must remove all of the output files to trigger the tests to run
again e.g. `find . -name '*.out' | xargs rm`.

If you run the install as root you will need some assurances
that you can recover your system, and statically linked
executables are one assurance.

What documentation are you reading that says to use `install_root`?

As a GNU project we conform to the GNU Coding Standards.

Does installing with DESTDIR (as documented) do what you need?

e.g. make DESTDIR=/tmp/stage1 install
