Thanks!

After fixing the default in meta-qt5 I've started to see this issue in
other builds which were indeed built with
PREFERRED_VERSION_readline ?= "5.2"
to prevent GPLv3 readline being used by other components.

For gdb which isn't part of our release builds we can use bundled
readline, so I had to apply this no-static-libs.inc change and
explicitly remove readline from gdb's PACKAGECONFIG.

So to recap, meta-qt5 change fixed my jenkins "bitbake world" builds by
enabling system readline.
For internal builds (without GPLv3 where possible) on the other hand I
need to remove readline from PACKAGECONFIG and apply this fix to build
static readline inside gdb's build.
