When using target board cc-with-gdb-index.exp and running tests in parallel, we run into: ... gdb compile failed, gdb/contrib/gdb-add-index.sh: line 86: \ build/gdb/testsuite/gdb.sh: Text file busy ... The problem is that because of the parallel test run, gdb.sh is created for every single test-case, and eventually gdb.sh is overwritten while being executed. Fix this by creating gdb.sh only once. Tested on x86_64-linux with target board cc-with-gdb-index.exp, using both a serial and parallel -j 5 test run. gdb/testsuite/ChangeLog: 2020-03-06 Tom de Vries <tdevries@suse.de> * lib/gdb.exp (tentative_rename, cached_file): New proc. * boards/cc-with-tweaks.exp: Use cached_file to create gdb.sh.
