[CCing Jakub]

Jakub committed a patch for this on Thursday to the gcc repository:

https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=a0ae4cbe9d1430b32f674b862a6d8dce0ed81f2a

which I believe ought to fix it (assuming the box in question is now
running RHEL 8).

The mailing list discussion was here:
  https://gcc.gnu.org/pipermail/gcc-patches/2020-March/541922.html

Does the updated script need to be copied over somewhere?
