/usr/bin/ld.gold: internal error in set_xindex, at ../../gold/object.h:1050
collect2: error: ld returned 1 exit status
`powerpc64le-linux-gnu-gcc' failed in phase `Linker'. (Exit code: 1)
In Ubuntu, the attached patch was applied to achieve the following:
* Disable LTO on the ppc64el architecture (LP: #2033639)
Thanks for considering the patch.
