/* If symbol SYM is in a mergeable section, relocations of the form
SYM + 0 can usually be made section-relative. The mergeable data
is then identified by the section offset rather than by the symbol.
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. */
