Bug 1295: Add linux-aarch64 GNU/Linux AArch64 crosscompile support

make/lib/gluegen-cpptasks-linux-aarch64.xml:
  Add missing -DisLinux=true required when crosscompiling
  Remove -marm -mfloat-abi=hard flags unrecognisable by aarch64 crosscompile toolchain

make/lib/toolchain/aarch64-linux-gnueabi/bin/*:
  Symlink to /usr/local/x-tools/aarch64-unknown-linux-gnueabi/bin/aarch64-unknown-linux-gnueabi-*

make/scripts/make.gluegen.all.linux-aarch64-cross.sh:
  New crosscompile script

make/stub_includes/platform/glibc-compat-symbols.h:
  glibc 2.17 is the first glibc version that support aarch64
  however memcpy is not versioned for aarch64
  Disable versioning for linux glibc/aarch64
