Please make it a generic solution for a generic problem. I have cases
that each psABI may want to do things differrently. I suggest a generic
node section:

        .section       .note,".note-ABI-tag"
        .align          2
        data4           .L1 - .L0
        data4           .L3 - .L2
        data4           1
.L0:
        stringz         "Compiler vendor"
.L1:
        .align          2
.L2:
        data4           ABI flags
.L3:
        .align          2


The linker provides a generic routine to process it. Each psABI can add
additional bits to ABI flags and decide how to process them.
