[Buildroot] [RFC PATCH 0/2] add gobject-introspection

[Sam Bobroff <sam.bobroff@au1.ibm.com>]

Hi Buildroot,

Here's my attempt at the gobject-introspection package, presented for comments.

The basic design is:

* Build host-gobject-introspection normally, but slightly patched to allow an
  alternate "ldd" to be used (this handles it's use of "ldd", it already has a
  way to add a wrapper when it directly executes binaries).
* Manually construct some wrappers in the staging
  directories so that it can be used from there on target packages (via QEMU
  usermode).
* Build the target packages that use gobject-introspection using the wrappers
  in staging.
* Build the target version of gobject-introspection (I think this is necessary
  at run time, but I can't remember for sure).

The part I'm least happy with is the ldd-cross script, and the way it has to
scrape information out of "/usr/bin/ldd" to find the target's dynamic linker.
Is there a better way to find the dynamic linker in the target?

Note: ldd-cross can be useful separately, as it lets you easily inspect target
binaries from the host. Perhaps it should be it's own package?

I've included a patch to a random package (libvips) that uses
gobject-introspection to enable it's use and exercise build dependencies.

I'm sure it needs more cleanup, but at least it works.

Cheers,
Sam.
