I'm still getting segfaults here.
The way I am testing is building a Yocto Project (jethro) system
core-image-base, and adding to it:
"packagegroup-core-buildessential,libelf,elfutils-dev,binutils-staticdev,glibc-staticdev"
The copying a checked out version of the prelink-cross repository with the
prelink_cross_aarch64 branch checked out.
On the target:
autoreconf -if
./configure
make
make -C testsuite check
Most tests still fail, and all of the TLS tests result in a segfault.
(I do have the 'aarch64/dl-machine.h: Fix load-address for prelink support'
applied to my glibc. Are there any other patches that may need to be applied?)
