--- Comment #1 from Chris Packham <judge.packham+glibc at gmail dot com> ---
Alan Modra explained on the binutils mailing list:
Around 2007, the powerpc ABI (and gcc and binutils) gained what I
called secure-plt. Prior to that, the powerpc plt section was a bss
section that was written with code generated by ld.so. This required
a section that was both writable and executable, and therefore
somewhat of a target for malicious code. The new secure-plt ABI
doesn't use an executable plt, but the code generated to make a call
via the plt is a little slower than bss-plt in moderately sized
executables and libraries. Your gcc might be configured to generate
bss-plt code by default, so to use ld.gold when linking shared
libraries or PIEs you'd need to pass -msecure-plt to gcc when
compiling. If your project has assembly that makes bss-plt style
calls then more work will be needed.
