Subject: [patch, testsuite] check for readline support in
	gdb.base/history-duplicates.exp

The testcase gdb.base/history-duplicates.exp checks the interaction 
between "set history remove-duplicates" and scrolling back through 
command history with ^P, thus it only makes sense if readline support is 
present.  I've copied the test that currently appears in readline.exp 
and other places.  OK to commit?
