Fix makefile to build on a Windows host PC
The TF-A firmware build system is capable of building on both Unix like and Windows host PCs. The commit ID 7ff088 "Enable MTE support" updated the Makefile to conditionally enable the MTE support if the AArch64 architecture revision was greater than 8.5. However, the Makefile changes were dependent on shell commands that are only available on unix shells, resulting in build failures on a Windows host PC. This patch fixes the Makefile by using a more portable approach for comparing the architecture revision.
