Looks like my Python knowledge is still too limited.
What is the problem with these lines?

oldflags = conf.env['EXTRA_LDFLAGS'];
conf.env['EXTRA_LDFLAGS'].extend(["-liconv"])
[...]
conf.env['EXTRA_LDFLAGS'] = oldflags

Looking at the logs, EXTRA_LDFLAGS still seems to contain "-liconv" as
if oldflags was not a copy, but a reference.
Or am I getting this wrong?

Cheers,
Christian
