Description Mark Hatle 2016-08-20 00:56:58 UTC 
The prelink test suite has two tests (reloc8 and reloc9) that attempt to link an application with "-Wl,-z,nocopyreloc".  This worked through "krogoth" but no longer works on master.

The easiest way to reproduce the problem is to build a system using the default 'master' configuration, adding:

IMAGE_INSTALL_append = " packagegroup-core-buildessential ssh sshd binutils-staticdev elfutils gdb file git"
EXTRA_IMAGE_FEATURES_append = " dev-pkgs"
IMAGE_ROOTFS_SIZE = "524288"

then build using:  MACHINE=qemuarm bitbake core-image-base

Boot into the system, and clone (using git) "git://git.yoctoproject.org/prelink-cross"

The run the following:

autoreconf -if
./configure
make
make check

The reloc8 and reloc9 test used to pass, and no longer do.  (It is expected there will be two failures, the preload1 and quick2 tests.)

We should retest to see if this is still a problem.

Prelink support has been dropped:
