+[PATCH] add checking for AArch64 ilp32

+Cross-compiling qt4-embedded and qt4-x11-free applications for AArch64 ilp32
+(both big and little endian) fails with below error,

+-- CUT --
+
+the error is because of JSVALUE64 is being defined while compiling programs
+for AArch64 ilp32. This makes equal condition checking of intptr_t and double
+datatypes as false, and results in -1 (negative) as array size in bitwise_cast
+function.
