Add also new comments for the new INSTALL flags.

I tried to use "hasgot" to test it but proved too difficult since you
must #include <winsock2.h> to make link succeed (windows magic) which
then makes gcc complain about the prototype being wrong.
Since windows already needs a special case in order to add -lws2_32 and
since we know for sure it will be available, skip the hasgot test and
check $target directly.
configure: add a special case to test for BSD sockets for mingw.

While at it also re-add two spaces that were eaten.

The test tried to do something like:
case "$foo,$bar" in
*,*) echo 1 ;;
*) echo "compiler not working" ;;
esac
However the second case cannot match because of the first one.
Instead, check the return code of the command.

This makes messages to the user more consistent.
Behaviours:
inf(): writes its arguments to stderr
wrn(): writes "[WARNING]" to stderr and then its arguments to stderr
err(): writes "[ERROR!]" to stderr, then its arguments to stderr, and
calls "exit 2"

Fails to compile alt-ergo without frame-pointers. No time to debug
before tonight, so I revert and will merge again after fixing the
problem.

This option can be used to tell the native compiler that it should
update frame pointers, so that debuggers and profiling tools
(especially Linux perf) can use them. For now, it is only supported
by the Unix/amd64 port.

Mac OS X ships with a really old version of as, which does not support
the CFI directives. LLVM itself provides an assembler that is certainly
way more up to date, but currently there's no dedicated frontend, so we
simply use clang in this case.

before calling into C functions, raising a Stack_overflow exception
otherwise. This reduces (but does not eliminate) the risk of
segmentation faults due to stack overflow in C code.
Implemented for i386, amd64 and power, under Linux and MacOSX.
Plus: remove some more stuff related to obsoleted platforms (IA64, SunOS 4).

Initial merge of the new ARM backend (commit ec5b444c7f) from my development
repository at https://github.com/bmeurer/ocaml-arm/tree/ec5b444c7f .
Compared to the old ARM backend, this one does the following:
- Support for both software and hardware floating-point (VFPv3).
- Properly supports interworking with Thumb/Thumb-2 code for both OCaml and C
code.
- Supports dynamic linking and large memory models (PR#5049).
- Optional support for position-independent code via a command line option
-fPIC. This is disabled by default and not required for natdynlink.
- Can emit both ARM and Thumb-2 code, with avg. code size savings of 28% for
Thumb-2 (quite close the optimal 30% advertised by ARM Ltd.).
- Supports both AAPCS (armel) as well as extended VFP calling conventions
(armhf).
- Supports several special ARM instructions to reduce code size and latency.
- Uses standard ARM EABI runtime functions instead of relying on GCC internals.
- Supports exception backtraces.
- Supports profiling using gprof.
