power 10 buildbot gdb build fail, no c++11 support

[Tom de Vries]

Hi,

I noticed this new failure: 
https://builder.sourceware.org/buildbot/#/builders/166/builds/798

The build fails due to no c++ compiler with c++11 support.

Could this be a system problem?

Thanks,
- Tom

Hi,

Not clear, .. It looks like gcc-c++ and libstdc++-devel were recently (10-18 pm)
updated on the host, and may have contributed in some way to something.  Those
packages appear to be installed OK, my manual builds are able to find things OK.

My manual configures are able to determine c++ support OK.

Per the logs, it looks
like the pkg-config check for version 0.9.0 or better has also failed, though my
manual configures are successful, and pkg-config itself shows as version 1.8.0. 
Either this was a transitory issue as reported in the logs, or the buildbot is
managing to not find the system headers that my manual builds are using.
