Correct.

How about this?

* Support testing glibc build with a different C compiler or a different
  C++ compiler from the C and C++ compilers used to build glibc with

  $ ../configure TEST_CC="gcc-6.4.1" TEST_CXX="g++-6.4.1"

  And support testing glibc build with Clang

  $ ../configure TEST_CC="clang" TEST_CXX="clang++"

  Some run-time failures with Clang are expected.
