Guile scripting support is not enabled in Ubuntu's build of GDB

Guile is the standard extension language of the GNU project, yet GDB (which is the GNU Debugger) in Ubuntu doesn't include support for it, which is unfortunate. I'd like to request that its support be enabled in the GDB build of Ubuntu/Debian.

$ gdb

(gdb) guile (display "hello world!\n")
Guile scripting is not supported in this copy of GDB.

Description: GNU Debugger
 GDB is a source-level debugger, capable of breaking programs at
 any specific line, displaying variable values, and determining
 where errors occurred. Currently, gdb supports C, C++, D,
 Objective-C, Fortran, Java, OpenCL C, Pascal, assembly, Modula-2,
 Go, and Ada. A must-have for any serious programmer.
