As new compilers generate this error we disable it for now as a
WORKAROUND. This will be removed when openjdk-8 is updated to the latest
version

Similar to the aarch64 build, we import the specific aarch32 port when
building for ARMv7. We also add all the necessary patches to:
* compile using gcc v8
* compile against musl
This was tested on:
* QEMU with cortex A7 emulation (using glibc)
* real hardware (using musl)

As a simplification for the upcoming aarch32 port.

Using gcc-8, Hotspot is being miscompiled, resulting in non-
working binaries.
The reason is undefined behaviour, which gcc-8 even warns about
and errors out. We have so far have taped over those warnings,
but it turns out that we simply cannot do that.
Add patches to address undefined behaviour causing miscompilation
of hotsport.
This also means we can remove the -Wno-error=return-type C compiler
flag again which was recently added in error in
commit 52fb41cec7d5 ("openjdk-8: fix build for gcc8.x") only hiding
the compiler warnings/errors that were flagging the incorrect code
in the first place.
With these patches applied, the openjdk-8 ARM port works again:

| SUMMARY:
| openjdk-8-test-image () - Ran 9 tests in 50.263s
The java.JavaTest.test_java_jar_comp_mode failure can be ignored for now,
as that test verifies compiled mode which is not available on arm. The
testcase must be fixed instead.
(We need to refresh one unrelated existing patch to avoid patch fuzz warnings)
