Hi,

I ran into this error:
...
ERROR: tcl error sourcing gdb/testsuite/gdb.arch/i386-pkru.exp.
ERROR: missing "
    while executing
"untested ""
    invoked from within

    (file "gdb/testsuite/gdb.arch/i386-pkru.exp" line 25)

...

Fix the unterminated string.

Tested on x86_64-linux.

Committed to trunk.

Thanks,
