This patch adds a switch --with-libgcc to configure.
When passed it prevents libtcc1.a from being built and links to
/lib/libgcc_s.so.1 instead of PREFIX/lib/tcc/libtcc1.a.
It will work on ARM when using libgcc from GCC >= 4.2.0.
Prior versions don't have the __floatun[sd]i[sdx]f functions.
It won't work on i386 because of two missing symbols emitted when
floats are cast to integers, but users can provide those symbols
(global short constants) in their code if needed.

This patch is useful for cross compilers. Without this patch tcc
tries to use the host's libraries, crt*.o and include files.
The patch prepends a string to all default paths. The string can
be passed to configure with --sysroot=string.

- Builds all four possible ARM targets when cross compiling
- Adds some auto detection to select the target for native ARM builds
The auto detection will select EABI if it finds /lib/ld-linux.so.3.
It will select VFP floating point support when /proc/cpuinfo lists
a VFP or iWMMXt coprocessor. Intel Wireless MMX does not imply VFP,
but it conflicts with FPA, so VFP is the only choice (apart from
yet unsupported soft-float).

Yesterday I felt the urge to change a few things in TinyCC.
This is the first and biggest change of all of them.
- use __aeabi_*divmod functions in ARM EABI to make binaries depend
solely on standardized library functions
- refactor ARM floating point <-> integer conversion a bit
- rename long long->float and shift library functions to correspond to
the names used by GCC
- compile more tokens conditionally to reduce the size of TinyCC
The intention is primarily to allow users of the ARM target to use
libgcc (which is usually available as a shared library) instead of
libtcc1 (which can't be compiled for ARM due to lack of an inline
assembler).
Changing the EABI target to use the divmod functions in theory allows
to use it without libtcc1 on any (not necessarily GCC based) ARM EABI
system.

- Hanging tcc -E
- Crashes witn global 'int g_i = 1LL;'
- include & lib search paths on win32
Added quick build batch file for mingw
Reverted case label optimization
(See Changelog for details).
