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

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.
The patch defines JSVALUE64, if the programs are being compiled for
AArch64 64bit NOT for ilp32.
2. qt4_arch.inc is modified to set system architecture as aarch64 if the
TARGET_ARCH is other than aarch64. Without this modification, for
TARGET_ARCH equal to aarch64_32, aarch64be, aarch64be_32; the system
architecture is set as 'generic' and results in below error.
