Use abspath to dereference $BUILD_BASE

Browse source 
If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.

This patch also adds documentation that BUILD_BASE can be specified by
the user.

- ``BUILD_STRING``: Input string for VERSION_STRING, which allows the TF-A
build to be uniquely identified. Defaults to the current git commit id.

addition to the options set by the build system.
