Handle PPC64 function descriptor in Ada decoding
On PPC64, the entry point of the function "FN" is ".FN" when a function
descriptor is used. One of the consequences of this is that GDB then
presents the name of the function to the user (eg: in backtraces) with
the leading dot, which is a low-level internal detail that the user
should not be seeing. The Ada decoding should strip it.
gdb/ChangeLog:
* ada-lang.c (ada_decode): strip dot prefix in symbol name.
No testcase added, as a number of existing testcases should already
demonstrate that problem.
