It looks like my questions about this patch never got an answer, and
it never got applied.
Could somebody say whether TLS is enabled for native *-*-mingw*
builds? If it is, then we definitely need to add GCC_CHECK_TLS to the
cross-compiler config too.
For a linux-hosted x86_64-w64-mingw32 cross compiler I see TLS is not enabled:
/* Define to 1 if the target supports thread-local storage. */
/* #undef _GLIBCXX_HAVE_TLS */
