ARM related Makefile changes

- 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).
