[PATCH v2 0/2] Opt-out static C++ link check and tests

["H.J. Lu" <hjl.tools@gmail.com>]

The current glibc build and test will fail if static C++ link doesn't
work.  There are cases where static C++ link is hard to supported:

1. Building i686 glibc with GCC 6.4 on Fedora 40 failed since the C++
header files couldn't be found which was caused by the static C++ link
check failure due to missing __divmoddi4 which was referenced in i686
libc.a and added to GCC 7. 
2. Glibc test won't finish because static C++ tests fail when the C++
toolchain doesn't have necessary static C++ libraries which may not be
easily installed.

Add --disable-static-c++-link-check configure option to disable the static
C++ link check.  Add --disable-static-c++-tests option to skip the static
C++ tests which also implies --disable-static-c++-link-check.

H.J. Lu (2):
  Add --disable-static-c++-link-check option [BZ #31412]
  Add --disable-static-c++-tests option [BZ #31797]
