Attached a patch to replace the test for macro __NEWLIB__ with a test for
macro NEWLINE_IN_CLASS_BLANK, defined by
   { dg-additional-options "-DNEWLINE_IN_CLASS_BLANK" { target newlib } }

Tested with check-target-libstdc++-v3, with the modified tests, for
arm-none-eabi and aarch64-none-linux-gnu.

Does this look ok to commit?

Not valid for approval, but that's what I meant!
Modulo the typo forgetting to
s/__NEWLIB__/NEWLINE_IN_CLASS_BLANK/ in the ifdef in
wchar_t/isctype.cc of course.

Attached the fixed patch.
Tested by running check-target-libstdc++-v3, with the modified tests, for arm-none-eabi and aarch64-none-linux-gnu.

Ok to commit?
