I didn't see the same failures. For example, for
hppa64-hp-hpux11.11, I only see

FAIL: ld-elf/linkoncerdiff
FAIL: ld-elf/pr11304

Some linker compress test failures are due to the
default linker scripts which don't support debug sections.
I have no plan to investigate them unless they
are caused by my compress change.
