Parse the comment block above each module or assignment looking
for directives in the form:
Android.mk:<directive>
If a block delimited by start and end directives is found, use it
as the Android.mk translation instead of trying to automatically
translate. If an ignore directive is found, ignore the module
completely.

Instead of putting errors into the translated Android.mk file where
they are unlikely to be seen and may cause strange build behavior,
make all errors fatal. Also buffer to a byte buffer and then write
to the output file once we are sure there are no errors.
