build: use toolchain identifiers in conditions
The toolchain refactor change introduces the `${toolchain}-${tool}-id`
variables, which provide identifiers for all of the toolchain tools used
by the build system. This change replaces the various conditions that
are in use to identify these tools based on the path with a standard set
of comparisons against these new identifier variables.
