Unfortunately, I found today one more complication with the relocations
against .L symbols in SEC_MERGE sections, because ld -r screws this up
(two .o files ld -r'ed together can use the same .L symbol name for
different strings).
So I'm wondering whether it is better to add yet more generic changes
(basically SEC_MERGE merging would have to be done during ld -r as well,
plus ld -r would have to create new local symbols on the fly into the
SEC_MERGE sections (because the old ones from input objects may clash)
and change relocations against local symbols in SEC_MERGE sections to be
against the newly on-the-fly created symbols.
This looks horribly to me, so I wonder if it would not be better to actually
touch all elf*.c files (the required change would be just a couple of lines
on at least the vast majority, perhaps mips would be harder).
Will code it tomorrow and mail it here.
