Hi all,
I've been trying to compile qt5declarative from the master branch of
Buildroot (8d56423d3d2308c620e61a952e36999c89e4d682
"package/zstd: observe Buildroot optimisation flags") on Fedora 34 without
success.
Here's the log:

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/qschulz/work/upstream/buildroot/output/host/aarch64-buildroot-linux-gnu/sysroot/usr'.
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

On Fedora 34 (probably 33 and earlier too), gcc package does not bring
libatomic so it is absent from the host rootfs.
```
$ find /usr -name "libatomic.so*"
/usr/lib/gcc/x86_64-redhat-linux/11/32/libatomic.so
/usr/lib/gcc/x86_64-redhat-linux/11/libatomic.so
$ cat /usr/lib/gcc/x86_64-redhat-linux/11/libatomic.so
INPUT ( /usr/lib64/libatomic.so.1.2.0 )
```
After installing libatomic from the package repository (c.f.
https://fedora.pkgs.org/34/fedora-updates-x86_64/libatomic-11.2.1-1.fc34.x86_64.rpm.html)
qt5declarative builds just fine.
In a (successful) build done on Debian Buster, I can see that qmltyperegistrar
is supposed to be built for the host.
Here are the .pro and resulting Makefile:
```

[full makefile can be found here: https://paste.ack.tf/a77eed]
From the logs and also the Makefile, it seems that qmltyperegistrar is
built with the wrong -spec passed to qmake. It should be
common/g++-base.conf (or something similar) and not
devices/linux-buildroot-g++ as currently.
This is confirmed a bit later in the Makefile with `-latomic` making it to LIBS
which might not be what's wanted?
This `-latomic` was added in
7d286be4f96cfb731e184c3e8cfea27a031bde3c "package/qt5base: link with -latomic when needed".
Here's the minimal defconfig I used to reproduce the issue:
```
BR2_aarch64=y
BR2_cortex_a35=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_QT5=y
BR2_PACKAGE_QT5DECLARATIVE=y
```
Let me know if there's anything I can do to help,
Thanks,
Quentin

After a lot of analysis I come to the same conclusion.

We end up with $(HOST_DIR)/mkspecs/devices/linux-buildroot-g++/arch.conf that
looks like this:
-----8<-----8<-----
LIBS += -latomic
-----8<-----8<-----
Perhaps that should be changed into:
-----8<-----8<-----
!host_build {
LIBS += -latomic
}
-----8<-----8<-----
Can you give that a go, and if it works, create a patch?
Regards,
Arnout
