e0f7e196f2 cxx: don’t define stubs for __throw_* functions
If exception support is disabled in IDF, and libstdc++ tries to throw
an exception, it will call __cxa_allocate_exception which is replaced
with abort in IDF.

We have a dramatically size reduction of the RO-section in binary when using '__throw_'-stubs in GCC5
In the case of using GCC8, we are faced with 'multiple definition' errors when using '__throw_'-stubs.
Good that we don't have the size problem due to gcc8

78ed138453 cxx_exceptions: Add missing stubs for cxx exceptions with exceptions
disabled

The misssing stubs get pulled in from the toolchain's libstdc++ also
causing to pull in defined stubs. This results in redefinition of
symbols. Fixing it by simply adding the missing stubs when exceptions
are disabled.
