I noticed that when testing glibc with a cross compiler I got
UNSUPPORTED: nptl/tst-thread_local1
because the libstdc++-v3 configuration for cross compiling defaulted
to __cxa_thread_atexit_impl not being available. This patch fixes
GLIBCXX_CROSSCONFIG to run the same test (for the case covering
targets with glibc) for __cxa_thread_atexit_impl as for native
compilation, just as it runs most of the other tests done for native
compilation (for these targets, it's not possible to build libstdc++
without already having built libc, so link tests are OK).
Tested with no regressions for cross to arm-none-linux-gnueabi.
