The mcs51 library target writes into ../build/$(PORT) without depending on it, so with -j the archiver can start before the directory exists and the toolchain build fails with sdar: ../build/small/mcs51.lib: No such file or directory It is intermittent: the same tree builds fine on a retry.

Parallel builds race: the library target writes into ../build/$(PORT) but does

not depend on it, so with -j the archiver can run before the directory exists:
|
|
|

sdar: ../build/small/mcs51.lib: No such file or directory
|

Give the target an order-only dependency on its output directory.
