Linking with your .so files still doesn't give me any difference between
gold-2.39 and gold mainline. I'm using my crt*.o, libc_nonshared.a,
libgcc.a. From ld -t output it seems nothing from libc_nonshared.a or
libgcc.a is extracted, so the only real difference ought to be crt1.o,
crti.o, crtn.o, crtbegin.o and crtend.o. Please supply them too. For
reference the linker command line I'm using on my x86_64 to powerpc64le
cross compiler setup is:

This is the command line passed to the linker by g++-12 as shown by
adding -v to the g++ command line, with unneeded plugin and library path
stuff removed and modified to pick up your shared libraries.

With bfd everything works, with gold, I get a Segmentation Fault.
(Ubuntu mantic development release)
First broken version is 2.40-2ubuntu5
Last working version is 2.40-2ubuntu4
According to the diff only one powerpc change was added on gold linker
http://launchpadlibrarian.net/664314947/binutils_2.40-2ubuntu4_2.40-2ubuntu5.diff.gz
And its this one
