1) use " instead of ' to expand variable
2) fix x86 arch autodetection (android toolchain doesnt use _X86_)

Classic/6G: CPU frequency/voltage scaling

This patch implements HAVE_ADJUSTABLE_CPU_FREQ, it modifies the
following parameters when CPU is unboosted:

- s5l8702 voltage is decreased: 1.200V -> 1.050V
- CPU frequency is divided by 4: 216MHz -> 54MHz
- AHB frequency is divided by 2: 108MHz -> 54MHz

Remove espeak from TTS list on Windows.

On Windows espeak installs itself as command line program as well as as SAPI
voice. Using the SAPI voice is simpler, so there is no need to keep the command
line option for it.

Disable _FORTIFY_SOURCE for the simulator

Most of our code was written to be efficient. While adding return value
checks everywhere would be a good idea in theory, it would increase binsize
a lot, and #ifdeffing those checks for sim-only is not doable. Disabling
_FORTIFY_SOURCE makes the warning disappear for innocent commits that
can't be blamed for them.

Revert 1207c7b and fix the actual warnings.

The warnings 1207c7b was supposed to get rid of are sim-only. This
means the binsize argument used for the _FORTIFY_SOURCE fix did not
apply at all. This one actually checks the return values.

More completely flush WMA decoder state on seek to prevent artifact.

Each MDCT depends on the previous frame for reconstruction.  Previosly these were not zeroed out when seeking, resulting in a few milliseconds of the previous frame playing with the current one.  Fix that.

Additionally, since the codec treats seeks to the start of a track as a "reset", flush the entire codec state in this event to ensure that everything is reset.

__get_sp is missing a return! I don't know how it ever worked.
Use "bx lr" since it works in all cases (armp and thumb).

touchscreen: Fix kinetic scrolling when the statusbar is off.

The scrolling code cannot differentiate between the BUTTON_TOUCHSCREEN post
from normal touches and the one posted in the timeout callback.

To fix introduce a global special button (BUTTON_REDRAW) that results
in the desired redraw. This existed already as a local kludge for android
and is now generalized.

arm: factor all exception handlers out of the crt0.S files

Remove the implementations of all exceptions handlers from the
various crt0.S files and have a single implementation in system-arm.h
The new implementation is weak so that it can be overwritten by some
specific code (like the unwinder)

arm: implement safe reads by intercepting the data abort handler.

Implement functions to read from a memory location and indicate
failure in case this is not possible. Since we do not have a MMU,
intercept the data abort handler and simply return when the abort
comes from the safe read routines.
