Ubuntu/Debian defaults PIE to enabled. This causes the trace tests to fall over due to variables being returned as "unavailable". The tests were never designed to work with pie. Simply ensure the nopie flag is always used for the failing tests. This removes 100+ failures when running native-gdbserver on Ubuntu 18.04. gdb/testsuite/ChangeLog: * gdb.trace/backtrace.exp: Use nopie flag. * gdb.trace/circ.exp: Likewise. * gdb.trace/collection.exp: Likewise. * gdb.trace/ftrace.exp: Likewise. * gdb.trace/mi-trace-unavailable.exp: Likewise. * gdb.trace/mi-traceframe-changed.exp: Likewise. * gdb.trace/qtro.exp: Likewise. * gdb.trace/read-memory.exp: Likewise. * gdb.trace/report.exp: Likewise. * gdb.trace/tfile.exp: Likewise. * gdb.trace/tfind.exp: Likewise. * gdb.trace/unavailable.exp: Likewise.
