Paul E. Murphy 86005fdbf4 ldbl-128ibm-compat: workaround GCC 9 C++ PR90731 
GCC 9 has a bug (PR90731) whereby __typeof does not correctly copy
exception specifiers[1].  Surprisingly, this can be quieted by declaring
"#pragma system_header", or if the headers are installed in a system
directory.

Work around this by using the pragma for any gcc version between
9.0 and 9.2 to ensure tests continue to compile.

[1] Example error from g++ 9.2.1:
