Hi!

I started using scripts/build-many-glibcs.py to do scheduled CI builds
with --full-gcc and noticed that in my setup (fairly new host GCC
version, and a small patch to use all-trunk versions for all relevant
sources from a local GIT mirror), I run into an issue with gcc-first:

I found a long-standing PR for GCC:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100289 .  Maybe it would
be okay to pass --disable-gcov to overcome this?



This gets me past this build step.

Thanks,
  Jan-Benedict

It is not clear on the bug report whether this is gcc bug or the intended way to
bootstrap.  Either way, I think it should be fine to disable it on bootstrap
(it is unlike we will need a gcov enabled stage 2 gcc and if it is really
required a stage 3 might a better way to accomplish it).
