[OE-core] Parse errors introduce by qt4 python->shell style functions

[Anders Darander]

Hi,

I recently started to look at updating our internal repos using the
latest denzil updates.

However, this introduced parse errors for us. We got a bbappend for
qt4-embedded, which includes a number of lines like:

QT_CONFIG_FLAGS := "${@oe_filter_out('-plugin-gfx-transformed', 
'${QT_CONFIG_FLAGS}', d)}"

(this is to remove lots of features, both size-wise and to reduce build
time).

This work fine up to the original denzil release. Now I've run a bisect,
and found that our problems was introduced by "qt4: move functions from
python to shell style", commit id:
98cb2efe4e9f3092d531c9fc809406c3ef559725.

After this commit, we get errors like:
$ bitbake core-image-sato -eLoading cache: 100%

triggered exception SyntaxError: EOL while scanning string literal
(QT_CONFIG_FLAGS[:=], line 1)
ERROR: Command execution failed: Exited with 1

Summary: There were 2 ERROR messages shown, returning a non-zero exit
code.

The change from python to shell style functions seems to require some
adaption of our bbappends, which I can't find...

Any ideas?

Thanks in advance!

Cheers,
Anders
