Quentin Schulz 4b6ce4604c meta: license: fix non-SPDX license being removed from INCOMPATIBLE_LICENSE
A non-SPDX license (which is not an alias to an SPDX license) cannot
currently be marked as incompatible in INCOMPATIBLE_LICENSE.
In the current state, we take all INCOMPATIBLE_LICENSE and pass them
through expand_wildcard_licenses which is only adding SPDX licenses that
match the glob regexp of what is in INCOMPATIBLE_LICENSE (be it a direct
match to an SPDX license or via an alias).

This does not work well with custom licenses.

E.g.:

foo.bb:
LICENSE = "FooLicense"

conf/local.conf:
INCOMPATIBLE_LICENSE = "FooLicense"

`bitbake foo`

Gives no warning, no error, builds and packages successfully, because
INCOMPATIBLE_LICENSE is basically empty since FooLicense is neither in
SPDXLICENSEMAP nor in SRC_DISTRIBUTE_LICENSES.

Let's add the original licenses to the list returned by
expand_wildcard_licenses to be able to handle the aforementioned case.

INCOMPATIBLE_LICENSE = "FooLicense GPLv2 GPLv3+" used to "resolve" to
"GPLv2 GPLv3". It now resolves to "FooLicense GPLv2 GPLv3 GPLv3+" which
fixes the issue with custom licenses not being in SPDXLICENSEMAP or
SRC_DISTRIBUTE_LICENSES and thus being left out of the blacklisted
licenses.

I needed to pass a list to expand_wildcard_licenses from the
license_image class instead of the current output of map() because the
operator [:] does not work on this kind of type, and list(map()) or
anything that iterates over map() actually moves the iterator and breaks
the forloop right after in expand_wildcard_licenses.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
