gnu-elf.ld.in named neither .rel.plt nor .got.plt, and the linker placed them where its FDPIC code does not expect them. It merged .rel.plt into .rel.dyn but still set DT_JMPREL as if .rel.plt came last, so the loader bound each PLT slot with the symbol of another relocation. And .got.plt came after .got: the offsets that the linker gave the local function descriptors did not match where it put them, and the first call through one jumped into data. A module without a PLT has neither section, so neither problem showed until a module called its imports through a PLT. Give .rel.dyn and .rel.plt output sections of their own, and put .got.plt first in .got, both as in the linker's own script. Only CONFIG_FDPIC changes.
