[PATCH] Allow gdb version 10 in pretty printer tests.

[Stefan Liebler]

With gdb 10, the pretty printer tests are UNSUPPORTED::
The gdb version string (gdb -v) is incorrectly formatted.

This is observable in:
nptl/test-cond-printers, nptl/test-condattr-printers,
nptl/test-mutex-printers, nptl/test-mutexattr-printers,
nptl/test-rwlock-printers, nptl/test-rwlockattr-printers

After updating the regexp and building with debug-info,
all those tests are passing.
