I'm currently involved in a cross compiling project for an ARM platform, and
for that purpose I installed the ARM toolchain from cross-arm-none-eabi.

However, linking fails because the libstdc++_nano.a is not included in
/usr/arm-none-eabi/lib, and I could not find a suitable package that would add
the missing libs.

This topic of the missing C++ libs in newlib appears multiple times on the web
with various options to fix it, but I am not too familiar with the whole topic
of cross-compiling chains to be able to find out which is the proper way to go.

What I could see is that the nano.specs file contains a rule to replace
-lstdc++ with -lstdc++_nano, although there is no such library.

Interestingly, I was successful on Ubuntu 22.04 (in a VM), its
/usr/lib/arm-none-eabi/lib (-> /usr/lib/arm_none_eabi/newlib) folder actually
contains libs like libstdc++_nano, libsupc++_nano etc.

Thus, for now, I am forced to compile the project in Ubuntu in the VM, instead
of natively on openSUSE.
