This problem is occurring because the file sysv.o has a writable .eh_frame
section. That is confusing gold's relro support. This is certainly a bug in
gold. However, there does also seem to be a problem in libffi. Why is the
libffi configure.ac setting EH_FRAME_FLAGS to "aw"?
As far as I can see, the test in libffi/configure.ac is bogus. It is compiling
code and looking for the setting of the .eh_frame section. However, the code
it is compiling has no need to handle exceptions and therefore has no .eh_frame
section. The configure script draws the wrong conclusion and emits a writable
.eh_frame section when it should emit a readable one. This should be fixed
independently of the gold problem.
