Allocate the first .plt entry space only if needed
Commit dd7e64d45b317128f5fe813a8da0b13b4ad046ae may optimize out
i386/x86-64 JUMP_SLOT relocation. If there is no JUMP_SLOT relocation
left, we don't need to the first .plt entry. This patch allocates
space for the first .plt entry only if we also reserve space for a PLT
slot for JUMP_SLOT relocation.
