Fixed fdlibm on x86_64: must have #define'd __LITTLE_ENDIAN on x86_64 too
Otherwise __LO() and __HI() macros are not working as expected, see
http://forum.world.st/fdlibm-is-not-C99-conformant-td3167570.html
This fixes FloatAndDoubleTests#test() on Linux/64bit on OpenJDK6
(which makes use of java.lang.StrictMath#floor() which was subject
to the bug)
