Rationale: https://sourceware.org/ml/gdb-patches/2019-08/msg00651.html
This very simple patch removes the "\nError: " suffix from the warning
message printed by nat/fork-inferior.c:trace_start_error. This proved
to just pollute the screen, causing things like:
Starting program: /usr/bin/true
warning: Could not trace the inferior process.
Error:
warning: ptrace: Permission denied
This "Error: " string is not useful at all, and can confuse things,
therefore let's just remove it and simplify the resulting messages:
Starting program: /usr/bin/true
warning: Could not trace the inferior process.
warning: ptrace: Permission denied
