As per section 4.2.2 of the PowerPC ELFv2 ABI, this value tells the dynamic linker which optimizations it is allowed to do.
Specifically, the higher order bit of the two tells the dynamic linker that there may be multiple TOC pointers in the binary.
When we resolve any NOTOC relocations during linking, we need to set this value because we may be calling
TOC functions from NOTOC functions when the NOTOC function already clobbered the TOC pointer.
In practice, this ensures that the PLT resolver always resolves the call to the GEP (global entry point) of
the TOC function (which will set up the TOC for the TOC function).
