Generate build products in sub-directories
A single binary can be compiled using a command such as: make CROSS_COMPILE=aarch64-none-elf- bl1 Also make use of brackets consistent in the Makefile. Change-Id: I2180fdb473411ef7cffe39670a7b2de82def812e

The build creates ELF and raw binary files in the current directory. It

generates the following boot loader binary files from the ELF files:

The build process creates products in a `build` directory tree, building
