Thanks for your comments on the patch process. Currently I am not familiar
enough with git -after years of svn- to redo the patches in the proper
way.
(I just bought the Git book from O'Reilly book by Loeliger & McCullough)
Besides I copied them to my private email account, because we do not want
to reveal our company name -yet-

So please if somebody else can redo the patches that would be great.

Then, as I indicated, these patches were only prerequisites, which implies
more is needed right?
And yes, closed source GPU stuff is really annoying, especially if it
requires you to build an external toolchain with glib-2.13, for that's
what
Freescales's LTIB used.
But that is exactly what I did: an external crosstool-NG
(I spent 4 weeks trying to do without, but I could not get the stuff to
link properly)
As an aside: the new Qt5-5.0.2-base fails to build on linking errors
(vtable; that is link sequence problems)

To prevent this email from becomming to big I will only inline the
crosstool-NG config I used. I will put the modified Qt5-base.mk in a
seperate email.

By the way, I used the Freescale Linux distro, which revealed a problem
in Buildroot also: If a custom kernel tarball is used -possibly only-
together with crosstool-NG, that kernel does not get a make
linux-configure to fetch the headers needed to build the toolchain.
And as noted: the integration with crosstool-NG is not perfect, so the
external tarball location is not filled in.
So here is my toolchain/toolchain-crosstool-ng/crosstool-ng.config-glib
