+ This works fine for initialed data and text sections. In principle .bss is also
+ handled, but the name##_pb definition is not removed. Reason is, that
+ array definitions are placed in the COMMON section, by default
+ The attribute "nocommon" removes this automatic assignment to the
+ COMMON section and directly puts it into .bss. As a result, if more
+ than one buffer is defined in one file, then it will be removed with --gc-sections
+
+ .. not sure if Arduino IDE uses -fno-common... if yes, then the attribute is
