    ARM: Support hardfloat in SCons build and make it a build time setting · 00bc2db2
    sgjesse@chromium.org authored
    Add option armeabi to the SCons build for selecting the floating point variant to use. Also add externally defined CCFLAGS environment for all targets. Run test.py with option -S armeabi=hardfloat to test with hardfloat enabled.
    
    Make selecting hardfloat EABI variant a build-time option instead of a runtime option.
    
    Add a simple check of the EABI variant during V8 initialization to exit if the compilation was not configured correctly. The reason for this is that GCC does not provide a compile time symbol defining the EABI variant. This check is not fool-proof as it cannot check the compilation configuration used for the snapshot if any.
