SYM + 0 can usually be made section-relative. The mergeable data

However, if we're generating REL LO16 relocations, the offset is split

between the LO16 and parterning high part relocation. The linker will
|

need to recalculate the complete offset in order to correctly identify
|

the merge data.
|

|
||||
The linker has traditionally not looked for the parterning high part
|

relocation, and has thus allowed orphaned R_MIPS_LO16 relocations to be
|
||||
placed anywhere. Rather than break backwards compatibility by changing
|
||||
this, it seems better not to force the issue, and instead keep the
|

original symbol. This will work with either linker behavior. */
