[PATCH] Fix gdb.ada/O2_float_param.exp for PowerPC

[Carl Love <cel@us.ibm.com>]

GDB maintainers:

The gdb.ada/O2_float_param.exp for PowerPC test fails due to a
difference in the output of the frame command.  On PowerPC, the frame
command prints the address in addition to the rest of the information. 
The address is not printed on X86.  This patch updates the expect
string to account for the presence or absence of the address in the
output.

The patch fixes two failures in the test on PowerPC.  The patch has
been regression tested on Power 10 with no additional failures.

Please let me know if this patch is acceptable for mainline.  Thanks.

                     Carl 


----------------------------------
Fix gdb.ada/O2_float_param.exp for PowerPC

The frame command on Power pc prints the address in hex between the
#0 and in calle.increment.  For example

(gdb) frame
#0  0x0000000010010a88 in callee.increment (val=val@entry=99.0, msg=...)
    at /home/.../gdb/testsuite/gdb.ada/O2_float_param/callee.adb:19
19	   procedure Increment (Val : in out Float; Msg: String) is

Update the set re string to accept the hex address.

Fixes two failures on PowerPC.

Patch tested on Power10 with no new regressions.
