OK that is good :-)

The build system is Centos7 with bash;
GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu)

Not the newest but on the other hand Centos7/RHEL7 is a very stable
platform. It would be very nice if it could be part of the list of
platforms Pengutronix uses to test ptxdist ;-)

I found a missing dependency for libsoup, it needs glib host tools. I
am running from a minimal docker so those aren't available on the host
and so libsoup.in needed select HOST_GLIB

Maybe it is just caused by some other missing deps. 

BTW: wouldn't it be easier to add select HOST_GLIB to glib.in ? Or even
more general do that for all packages that have a host-* version ?

I'll look into it and report back when I know more, certainly now I
know -j really is a first class citizen :-)
