[Bug binutils/10337] New: strip breaks statically linked binaries with .rela.plt section

[jakub at redhat dot com]

On --enable-multiarch configured glibc if I do:

elf/ldconfig --version; \
/usr/src/binutils/obj/binutils/strip-new elf/ldconfig; \
elf/ldconfig --version

I get:
ldconfig (GNU libc) 2.10.90

unexpected reloc type in static binaryAborted

Before stripping we have:
...

(note non-allocated RELA section) and all 48 bytes between 0x1a0 and 0x1d0 in
the file are cleared.
