Fix: verbose build for external components

LazyFetch allows setting <upper case component name>_VERBOSE_BUILD
variable in the cache or in the environment to make the build emit all
build commands executed. This is not working as the code uses an
incorrect variable.
Fix the variable and make the feature work.
