Subject: [PATCH] Fix freestanding cstdint which fails to detect
stdint.h [PR100057]
Configure script cannot find cstdint when we build in freestanding
environment since there are no stdint.h header file.
However when we try to #include<stdint.h> directly, it works by
indirectly #include<stdint-wrap.h> which has been fixed by me if
the _GLIBCXX_HOSTED_ is defined as 0
The last patch is still required, this is to fix another issue.

PR libstdc++/100057
* libstdc++/include/c_global/cstdint:
Always #include<stdint.h> if _GLIBCXX_HOSTED_
== 0.
