testsuite: libstdc++: Use effective-target libatomic

Test assumes libatomic.a is always available, but for some embedded
targets, there is no libatomic.a and the test thus fail.

libstdc++-v3/ChangeLog:

* testsuite/29_atomics/atomic_float/compare_exchange_padding.cc:
Use effective-target libatomic_available.

[gcc r14-11207] testsuite: The expect framework might introduce CR in output

testsuite: The expect framework might introduce CR in output

When running tests using the "sim" config, the command is launched in
non-readonly mode and the text retrieved from the expect command will
then replace all LF with CRLF. (The problem can be found in sim_load
where it calls remote_spawn without an input file).

libstdc++-v3/ChangeLog:

* testsuite/27_io/print/1.cc: Allow both LF and CRLF in test.
* testsuite/27_io/print/3.cc: Likewise.
