[Patch] Cannot set pending bp if condition set explicitly

[Marc Khouzam <marc.khouzam@ericsson.com>]

Hi,

If I set a condition explicitly on a pending breakpoint (using
the 'condition' command), the breakpoint fails to install.

I believe it is because the condition is marked as parsed,
although, for a pending bp, this is not the case.
Note that using the form
  b mydll:c:5 if j==3
does work because the condition is not examined until the
pending breakpoint is installed.  This is not the case
when using the 'condition' command.
Broken session below.

No regressions on Ubuntu 32bit.

Is this ok for HEAD and 7_5?

Thanks

	* breakpoint.c (set_breakpoint_condition): For pending
	breakpoints, mark condition as not parsed.
