Title:
  Compiler gets stuck (or extremely slow) on ppc64el

Status in gcc:
  In Progress
Status in gcc-9 package in Ubuntu:
  Fix Released
Status in ghostscript package in Ubuntu:
  Confirmed

Bug description:
  I have uploaded Ghostscript 9.50 to focal and it built without any
  problem on all architectures but ppc64el. On ppc64el the compiler
  seems to get stuck (or extremely slow) on one of the files of
  Ghostscript (devices/vector/gdevpdfb.c, I tried twice). This leads to
  the build process being killed after 150 minutes.
