The modern MSVC for ARM always builds for thumb, and it can't be
disabled.
Also just use the default arch instead of trying to map the -march
parameter to MSVC's -arch parameter (which only takes the values
ARMv7VE and VFPv4).

configure: Fix check_exec_crash for ICL support
Conflicts:
configure
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Initial support for the ICL compiler on windows. Requires a new
c99wrap with ICL support (1.0.2+).
Currently not much different speed wise compared to msvc. In the
future with a few changes it can be made to support the inline asm.
This would be the primary reason for using it.
Passed all fate tests, versions tested:
13.1.1.171 (2013 Update 3) x86 and x64
12.1.5.344 (2011 Update 11) x86 and x64

Change the check_exec_crash test to use a function pointer instead of
simply calling the function. The EBP availability test will crash when
compiled with ICL likely due to compiler optimization shenanigans.
Originally the check_exec_crash code was moved out of main to fix a
problem with gcc's treatment of non-leaf main on x86_32. Libav already
moved the code out of main but the addition of the function pointer will
prevent any inlining which fixes the remaining problem.
A function pointer is used since it is compiler agnostic (as opposed to
say __attribute__ ((noinline)) which would only work with gcc compatible
compilers).

configure: msvc: Set the target windows version to XP if no target is set
Merged-by: Michael Niedermayer <michaelni@gmx.at>
MSVC 2010 (or more precisely, Windows SDK 7.0 which comes with MSVC
2010) sets _WIN32_WINNT to the constant for Windows 7 if nothing is
set. This could lead to the libav configure script detecting and
using functions only present in Windows 7 or newer, which in most
cases isn't desired. If the caller explicitly wants this, the caller
can add the _WIN32_WINNT define via --extra-cflags, setting the desired
version.

With the parameter --toolchain valgrind-massif, the configure
script sets reasonable defaults that can be overridden as explained
in the documentation.

This makes it consistent with the msvc builds which automatically set
the DEP and ASLR flags by default. There really is no good reason why
they shouldn't be set.
The fact that binutils does not set them on by default boggles the mind.

If this is explicitly disabled for win32/mingw, it should also
be disabled for cygwin, for consistency and for the same reasons
as for win32/mingw.

These platforms do not have any notion of PIC. On some compilers,
enabling pic produces a number of warnings.
This avoids trying to produce PIC loads in the ARM assembly - there
are no relocation types in PE/COFF that correspond to
BFD_RELOC_32_PCREL (R_ARM_REL32 in ELF).
As a side-effect, this avoids enabling PIC on mingw64, getting rid
of the warnings about PIC not having any effect on that platform.

This allows it to be overridden, either by the user on the command
line, or by other sections of the configure script.
