Hi Bartosz,
Thanks for your contribution. I haven't tested this one yet, but I have some
remarks.

Is there a good reason to put everything in a single package? We normally make
separate packages for everything. We also don't like putting things in a
subdirectory very much. So I'd expect three separate packages:
package/libserialport
package/libsigrok
package/libsigrokdecode
package/sigrok-cli
The first three would go in the Libraries -> Hardware Handling menu, while the
cli would go in the Packages -> Hardware Handling menu.

We usually put something like:
depends on BR2_USE_WCHAR # libsigrok->libglib2, libsigrokdecode->python3

We want a specific version so the build is reproducible. Preferably a tag, but
in this case I guess it would be a full commit ID:
e31f2c6b8b8f2b7e554df911cc9a3482b99632b4
But I understand you plan to do that as soon as the ACME drivers have been
accepted.
Or a tarball is even better. If you can convince upstream to create a release?
Same for the other packages of course.

If http is possible, that is preferable, because not all company firewalls
allow git to pass.

We usually but a comment why autoreconf is needed:
# git checkout has no configure script

Hm. I like it when code duplication is avoided, but for e.g. phpize we do
duplicate it. Not sure...

I see a lot of optional dependencies here. We prefer to handle them explicitly,
either disabling them:
LIBSIGROK_CONF_OPTS = \
--disable-libftdi \
--disable-libusb \
--disable-bindings
or handling them:
ifeq ($(BR2_PACKAGE_LIBFTDI),y)
LIBSIGROK_CONF_OPTS += --enable-libftdi
LIBSIGROK_DEPENDENCIES += libftdi
else
LIBSIGROK_CONF_OPTS += --disable-libftdi
endif
This makes sure that the build result is the same regardless of the order in
which things are built.
Note that there is also an optional dependency on glibmm, but it can't be
disabled. This should be handled like this:
ifeq ($(BR2_PACKAGE_GLIBMM),y)
LIBSIGROK_DEPENDENCIES += glibmm
endif
Same for python-gobject.
Check configure.ac for more.

The optional dependency on libsigrokdecode should definitely be handled here.
