[PATCH 7/9] [gdb] Ignore trailing whitespace in gdb/gdb-gdb.gdb.in

[Tom de Vries <tdevries@suse.de>]

In gdb/gdb-gdb.gdb.in we have:
...
gdb/gdb-gdb.gdb.in:22: trailing whitespace.
+set prompt (top-gdb)
...

The trailing space is significant.

Fix this by dropping the trailing whitespace check for this file.
