This reverts commit e9a55d9770.
Re-enables the use of LLVM_IAS=1. This was disabled in aosp/1559459 due
to a single time-based test failure. This test failure is not
reproducible locally. The failure has never been observed on newer
kernel versions either. We should consider disabling this test if we
observe further flakes.
Test: 1. apply this patch
2. build kernel image
$ BUILD_CONFIG=common/build.config.gki.x86_64 build/build.sh && \
BUILD_CONFIG=common-modules/virtual-device/build.config.cuttlefish.x86_64 \
build/build.sh
3. launch cuttlefish with custom kernel image
$ launch_cvd -kernel_path=/path/to/out/android-4.19-stable/dist/bzImage \
-initramfs_path=/path/to/out/android-4.19-stable/dist/initramfs.img &
4. run test
$ atest vts_ltp_test_\
x86:syscalls.nanosleep01_32bit#syscalls.nanosleep01_32bit -- --abi x86
Test was repeated 10 times locally, 0 failures observed.

This reverts commit 4c451dba25.
AOSP's distribution of GNU binutils always had a curious target triple
prefix on the binaries. Now that GNU binutils is deprecated for Android
Common Kernels, we can now remove this out of tree workaround. Now
building Android kernels with LLVM matches upstream (see
Documentation/kbuild/llvm.rst).

The build.config.* files largely contain duplicate information by their
nature. Reorganize them reduce duplication and to allow adding new
configurations without copying the definitions again.
