this would require a special attribute definition and special asm code and some
work in the ld.
Let me ask one question: Why do you like to make a new non standard way (2) to
mark such things where the section setting stuff (1) is already part of the gcc
standard.

In both cases an ld patch is necessary, so it seems to me, that 1 would be
lesser efforts.
