Failure to link a PIE binary on ppc64el (FTBFS)

[Sergio Durigan Junior]

golang-1.18 fails to link a PIE binary on ppc64el, which is causing FTBFSes in other packages (telegraf, in my case), including an FTBFS while building golang-1.18 itself on that architecture.

There's an upstream bug & fix available, and I intend to work on backporting them. I'll probably need to do a two-stage upload in order to be able to fully build the fixed golang compiler on ppc64el, though.

  * d/p/lp1973107-cmd-link-use-TOC-relative-trampolines-on-PPC64-when-.patch:
    Use TOC-relative trampolines on ppc64el when needed. Fix link
    error when building PIE binaries. (LP: #1973107)
  * d/rules: Remove link_test.go when running tests on ppc64el. This
    is a temporary change that will be reverted in the next upload.

I had to revert the patch in Kinetic because it was causing golang-1.18.2 to fail to compile itself on ppc64el. After some more investigation and help from upstream, I finally have the couple of patches needed to be backported in order to fix this bug fully.

That's why I'm setting this bug as In Progress again.

I did a test rebuild on Jammy, and the current golang-1.18 can build itself on ppc64el just fine:

Therefore, I'm:

- Lowering this bug's priority to "Low" on Jammy;

- Removing the server-todo tag;

- Unassigning this bug to myself, as I have other, more urgent things on my plate.

If someone feels like tackling this and backporting the fix to Jammy, feel free to ping if you need a sponsorship.
