While building Android with latest host gcc, it causes the following
build error:
Install: out/host/linux-x86/bin/mkbootimg
host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp
<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
<built-in>:0:0: note: this is the location of the previous definition
cc1plus: all warnings being treated as errors
In order to make build system happy, this patch does unset macro
_FORTIFY_SOURCE and then define it in host cflags.

This is needed in order to build Linux SDK binaries that can run
properly on Ubuntu 8.04 (Hardy). By default, the host toolchain
on 10.04 (Lucid) generates machine code that won't run on Hardy
due to GLibc ABI mistmatches.
Note that nothing happens if the new toolchain is not in the
prebuilt tree.

This detail got lost in my previous cleanup change 9b4a812.
Also add a comment explaining why the host side of the
simulator needs to be built in 64-bit (wxWidgets).

The only OS-ARCH combo that would have benefited from it
is linux-x86, but it explicitly used separate configurations
for the HOST_ and TARGET_ side of things.
This makes is clear which files are related to the HOST_
configuration and which ones are related to the TARGET_
configuration, and expands $(combo_target) to the only
possible/reasonable value that it could have had in every
file.
This also cleans up the simulator, by moving it in a single
place in TARGET_linux_x86 (since the only part that's special
is to use HOST_ settings even when building TARGET_ modules).
