It depends of what you are doing on your build script. The ‘make’ rule does
not run unit unit test, so if you intend to just build glibc it should be suffice.

However, if you are trying to run the expected make and make check you
try to not run the tests itself with the extra ‘run-built-tests=no’ rule with
‘make check’.

Unfortunately, there is no way to avoid specific tests in a default 'make check’
and this is intentional: a failure really should represent an issue that might be
investigated. 

We are trying to either get rid of flaky tests or improve them in a way to make
them report robust output, to avoid environment issues that might mislead
the runner.

What kind of issue are you seeing in you environment?
