1c3c269b55 Fix startup to security-relevant statically linked binaries.
Before the change they crash on startup.  Perform IREL relocations
earlier to prevent this.

443caceb35 Fix build problems with old binutils.
Old binutils don't provide IFUNC and don't generate the section start/end
symbols we expect.  At least for now only add the initializer code for
static IFUNC relocations if multi-arch support is requested.

7441470835 Finish IFUNC support for x86 and x86-64.
