[2/2] ARM64: Cross-Compilation Support

From: Krishna Kanth Reddy <krish.reddy@samsung.com>

Modified the Configuration file to use the latest ARM Cross-Compiler.

Fixed the linker errors for the undefined references to the APIs
isal_deflate_init, isal_deflate, isal_inflate_init, isal_inflate,
isal_inflate_stateless, isal_deflate_stateless,
isal_deflate_set_hufftables in the case of ARM Cross-Compilation.

According to https://developer.arm.com/downloads/-/gnu-a, there is no toolchain named aarch64-linux-gnu*.

All distribution OS packages use aarch64-linux-gnu* for cross compilation.
