[skip ci] I have confirmed that all 7 kernels still compile.
Builds abuild-sign and abuild-tar.static without any dependencies, so
they can be used outside of an Alpine Linux system. We need this for
build.postmarketos.org.
I noticed that some times the framebuffer driver gets configured in a
way that the ioctl performed by msm-fb-refresher returns something lower
than zero:
https://github.com/LineageOS/android_kernel_samsung_msm8974/blob/0ed263db093b1fc590589836ee36956c327998c3/drivers/video/fbmem.c#L877-L911
For example when the Xorg starts I noticed it does a ioctl BLANK and
UNBLANK, but if msm-fb-refresher performs a ioctl in that moment it
stops its loop and exit.
For this reason I lost a lot of time trying to understand what was the
problem with Xorg not displaying anything until I noticed that I had
to restart the msm-fb-refresher.
With this change we don't have to care about msm-fb-refresher as it will
continue call ioctl PAN even if the framebuffer returns some negative
error code.
Do not add --pixman-type to the commandline, when
deviceinfo_weston_pixman_type is filled out.
--pixman-type was enabled in Weston with a custom patch, that currently
prevents us from upgrading Weston (#136).
The option allowed working around broken framebuffer drivers in
Android downstream kernels, which reported the wrong color format.
But it only works for Weston, the right way to patch this would be
patching the kernels, and we have some approaches here:
https://wiki.postmarketos.org/wiki/Troubleshooting:display#My_screen_is_red.21
When rendering on framebuffer, always do software rendering. This
should make it possible to boot up Plasma Mobile on most devices with
downstream kernels, although terribly slow. Still better than a black
screen though. Tested and working on the samsung-i9100.
We can improve the code and possibly make the rendering mode
configurable per device once we experimented more with:
* llvmpipe vs. softpipe on various devices
* armv7 (around the corner in Alpine)
* a proper display manager like lightdm
Both depend on qt5-qtwebengine, which needs to be rebuilt in Alpine
after the soname bump of libavformat [1]. Disable them for now, so
plasma mobile can still be installed, and the pmbootstrap test case
that installs it runs through again.

Adjust the mime-type that gets used to find executables to
application/x-pie-executable and change the APKBUILD logic to print out
a meaningful error when the executables can not be found.
Also fix the broken patch logic (doesn't display an error anymore).
Fix Nexus 5 (hammerhead) boot and framebuffer issues at startup by
waiting up to 10 seconds until the rootfs and /dev/fb0 have been
found. Waiting for the framebuffer device can be disabled by setting
deviceinfo_no_framebuffer=true in the deviceinfo.
Copy Mediatek /emmc@partitionname symlinks to the chroot. This is
needed on Mediatek devices because the fstab file references the
partitions using those symlinks (which the kernel creates - for
whatever reason - in the root directory) and otherwise we don't know
which partition is which.
We used to put a "compiler-gcc6.h" file inside every vendor kernel's
aport. This is redundant and only works with GCC6. With this patch,
a common "compiler-gcc.h" file will be used, that works independently
of the GCC version.
The file is from Decatf's android_kernel_samsung_p4 repository, where
it was taken from upstream Linux, but adjusted to work with older
vendor kernels (different #ifndef check at the top etc).
