// SCUDO_HAS_PLATFORM_TLS_SLOT tells the Scudo sources to include this file
// and call this function instead of using a `thread_local` variable of its
// own.  Our current combined libc/dynamic linker implementation does not
// allow libc itself to have any `thread_local` variables of its own.  In
// future, a different dynamic linker implementation will likely remove this
// restriction and having scudo use a (hidden visibility) `thread_local`
// variable will work fine.
