rtems, like vxworks, uses fast-float doubles for from_chars even for
long double, so it loses precision, so expect the long double bits to
fail on aarch64.
Regstrapped on x86_64-linux-gnu, also tested on aarch64-rtems6. Ok to
install?
for libstdc++-v3/ChangeLog
* testsuite/20_util/from_chars/4.cc: Skip long double on
aarch64-rtems.

Disinformation flourishes because many people care deeply about injustice
