clean up a few semicolons in the build system

several code lines were condensed together, which
make them less readable. make the code more readable
by having separate commands on separate lines.

i previously did this during my manic build system
audits of 2023 and 2024; condensing lines like this
is overly pedantic and serves no real purpose.
