Fix manual dependencies

For some reason stdlib_ascii.o was not listed as a dependency under stdlib_io.o,
despite the fact that the stdlib_io module uses stdlib_ascii.o. This commit addresses
that discrepency. Furthermore, I cleaned up redundant dependencies under stdlib_math_logspace
and I fixed a formatting mistake that prevented the latest version 10 Ubuntu check from being
passed.
