BaseTools GCC: prevent unaligned memory accesses on ARM GCC 4.6
In GCC 4.7, a feature was added to the ARM backend that allows
unaligned loads and stores to be emitted. Since it is enabled by
default on ARMv6 and later CPUs, and since such code is not suitable
in our case (i.e., bare metal code), we must disable it by passing the
-mno-unaligned-access option if we are using GCC 4.7 or later.
However, this particular feature and its enabling by default have been
backported to version 4.6 by Linaro. Since the Linaro toolchains are
widely used for ARM development, and also shipped by distros such as
Ubuntu, we should disable the feature on version 4.6 as well.
Unfortunately, since the upstream version does not support the feature,
it also does not understand the -mno-unaligned-access option.
Since GCC sets the builtin #define __ARM_FEATURE_UNALIGNED to 1 when
-munaligned-access is in effect, we can force the build to fail in this
case by passing -D__ARM_FEATURE_UNALIGNED=0 on the GCC command line.
This will produce the following error message:
<command-line>:0:0: error: "__ARM_FEATURE_UNALIGNED" redefined [-Werror]
<built-in>:0:0: note: this is the location of the previous definition
and terminate the build.
This patch may cause some existing builds to fail, but they will be
builds that were previously at risk of unexpected runtime exceptions.
Those builds can also easily be switched to the GCC47 profile instead,
generating safe binaries.

After the recent GNU linker script changes, the following warning is

This is caused by the fact that, now that the section layout has changed
somewhat, the .eh_frame section is assigned an ELF segment of its own,
which ends up with no contents at all after we strip the .eh_frame
section from the output. (Note that the program headers that contain the
segment information are completely irrelevant to us since the PE/COFF
conversion does not rely on them.)
Since we only retain the .eh_frame data for external debugging, and not
for things like stack unwinding or generating backtraces at runtime, we
can remedy the situation by passing -fno-asynchronous-unwind-tables on
the GCC command line. This option instructs the compiler to emit the
unwind data into a debug section called .debug_frame instead of into
.eh_frame.

DHCP policy is applied as default at boot time on all NICs in the system, which results
in all NIC ports attempting DHCP and trying to acquire IP addresses during boot.
Ip4 driver should only set dhcp as default policy, and not trigger DORA at driver binding
start(). We should start DORA until one IP child is configured to use default address.

BaseTools: add CLANG35 toolchain with AARCH64 support
This adds support for building the AARCH64 platforms using the
Clang compiler and assembler combined with the GNU (cross-)linker.
The chosen name CLANG35 is based on version 3.5 being the oldest
supported version, but no issues are known that should prevent its
use with any later version.

BaseTools/GenFw: allow AArch64 tiny and small code model relocations
The AArch64 small C model makes extensive use of ADRP/ADD and
ADRP/{LDR,STR} pairs to emit PC-relative symbol references with
a +/- 4 GB range. Since the relocation pair splits the relative
offset into a relative page offset and an absolute offset into
a 4 KB page, we need to take extra care to ensure that the target
of the relocation preserves its alignment relative to a 4 KB
alignment boundary.
Also, due to a problem with the --emit-relocs GNU ld option, where
it does not recalculate the addends for section relative relocations,
the only way to guarantee correct code is by requiring the relative
section offset to be equal in the ELF and PE/COFF versions of the
binary. This affects both the 'tiny' and 'small' GCC code models.
