special .data.rel.ro section that contains a fake lzma_allocator
-the fake lzma_allocator makes lzma_alloc() call fake_lzma_alloc()
+the fake lzma_allocator makes lzma_alloc() call fake_lzma_alloc()
liblzma_la-crc64-fast.o lists the fields in the relocation table so that the linker fills out the fields with the offsets
lzma_allocator::alloc is the address of fake_lzma_alloc() the field maps to a relocation entry of type R_X86_64_64 and value fake_lzma_alloc
lzma_allocator::free is the address of fake_lzma_free() the field maps to a relocation entry of type R_X86_64_64 and value fake_lzma_free
