Hi,
Recently we found out that the .interp section starts to show up in
ARM executables compiled with "-shared -static" and the gold linker
from binutils 2.22. We tracked down the origin of the dynamic linker
commands and they are always explicitly specified in
config/arm/linux-elf.h. We tested the following simple patch to
suppress the dynamic linker options for statically linked programs on
Android's AOSP tree. Everything builds fine and the unneeded .interp
section is gone.
Thanks,
-Ben
