Converted ARMV5L from OABI to EABI with VFP support. Added patches for uClibc and uClibc++ to deal with Unwind Exception handling, made uClibc++ pull in libgcc_eh for this as well, and disabled SJLJ exceptions for ARMV5L EABI, which is apparently required, so --enable-sjlj-exceptions was added to the details file for all the other arches. Also correct the GENTOO_CHOST variable for armeb.
