There is nothing in that area that we changed between 18.0 and 18.1;
moreover, if we had broken something like that, it's highly unlikely
that nobody but you would have noticed.  You need to look at what
changed in your build environment.

gcc seems to be getting confused by the fact that src/test/isolation
contains a subdirectory named "specs", but that's been there for
years.  The most likely explanation is that some environment variable
is causing gcc to look in the current directory for its spec file
(although I don't see any documentation of such a variable in the
gcc manual).  It's also plausible I guess that you have a corrupted
gcc installation.
