Bug 2020479

Description of problem:

The (Fedora specific) GDB command "set build-id-verbose" is missing in gdb-11.1-2.  Likewise for the command "show build-id-verbose".

Version-Release number of selected component (if applicable):

gdb-11.1-2

Rawhide and Fedora 35 are currently affected by this bug. If/when gdb-11.1-2 reaches stable for F34, then F34 will also be affected.

How reproducible:

Always.

Steps to Reproduce:
1. Start gdb.
2. Type command "set build-id-verbose 1"
3. This command should succeed with no output.
4. Type command "show build-id-verbose".
5. This command show display: "Verbosity level of the build-id locator is 1."

Additional info:

Tom de Vries has provided us with a fix for this problem.

I'm creating this bug so that I have a bug number to use when doing a "fedpkg update".

Also, it should be noted that set/show build-id-verbose is implemented in a Fedora specific patch.  There is, at present, no equivalent command in upstream GDB.
