Disable support for packed relative relocs on i386/x86_64
the infrastructure for this requires the RELA relocations to
be idempotent. Our local patch binutils-revert-rela.diff changes
behaviour back to old behaviour in which they aren't anymore.
We require this for backward compat in the SLE codestreams.
Adjusting the infrastructure to deal with this isn't trivial, so
instead whole-sale disable the whole support for packed relative
relocs (and adjust testsuite for that).
This is necessary for at least glibc which tries to use them when
they seem to be available in the linker, which ultimately generates
wrong relocs (basically they are applied "twice").
