PATCH v3 1/1 core/pkg-generic: check proper package installation

Some packages misbehave, and install files in either of;
- $(STAGING_DIR)/$(O) or $(TARGET_DIR)/$(O),
- $(STAGING_DIR)/$(HOST_DIR) or $(TARGET_DIR)/$(HOST_DIR).

One common reason for that is that pkgconf now prepends the sysroot path to all the paths it returns. Other reasons vary, but are mostly due to poorly writen generic-packages.

And a new step hooks to check that no file gets installed in either locations, called after the install-target and install-staging steps.

Changes v2 -> v3;
- also check for $(HOST_DIR) in case the user specified an out-of-build-dir locatiopn (Arnout)

---
Note that, in the current state of Buildroot, this *will* cause a lot of build failures until all those packages are fixed. Among the known to break are quite a few Xorg packages, plus many packages that need to call moc (from Qt4 for sure, possibly from Qt5 too).

Hi Yann,

Still not true for moc :-)

You never replied to my comment that I think this would fit better directly in
the .stamp_install_* rules rather than as hooks. My reasoning is that it is much more difficult to find out why some commands are being called when they're hidden in hooks. That's not too bad for things like gathering statistics since they're supposedly inobtrusive, but here you're throwing an error so it is really useful to be able to find easily in the source where this error comes from.

Regards,
Arnout

Yeah. I was really off-tracks yesterday (hard day at $work, followed by yet another hard day)... Sorry...

And then how do you differentiate the error message?

But granted, we should probably do both checks here, like so:

    if [ -d $(2)/$(HOST_DIR) ]; then \
        printf "error... HOSTD_IR...n" >&2; exit 1; \

My reasoning is that it is much
more difficult to find out why some commands are being called when they're hidden in hooks. That's not too bad for things like gathering statistics since they're supposedly inobtrusive, but here you're throwing an error so it is really useful to be able to find easily in the source where this error comes from.

My reasoning is that I like hooks. ;-) After all, IIRC, I was the one to add them in the first place; I have to use them! ;-)

But OK, that potentially makes sense, like we do for the .la fixups.

I like the way you categorize hooks: they are for instrumentation (hence their names!). EVerything else you should go into the relevant command block.

I'll fix up and respin.

Thanks! :-)

Yann E. MORIN.
