Subject: [PATCH 1/1] Makefile.build: Add an explicit error for missing ASN.1 compiler

The current dependency rules mean that the build breaks if the ASN.1
compiler is required but CONFIG_ASN1 isn't set.  However, it isn't
obvious from the error message about missing files what the actual
problem is, so make the build system give an explicit error.
