It turned out that the linker was doing the wrong with the amalgamation library concerning weak stubs. A regression test has been added and new binaries have been uploaded to https://justine.lol/cosmopolitan/ Ideally this should be fixed by building a tool that turns multiple .a files into a single .a file with deduplication. As a workaround for now the cosmopolitan.a build is restructured to not include LIBC_STUBS which meant technical debt needed to be paid off where non-stub interfaces were moved to LIBC_INTRIN and LIBC_NEXGEN32E. Thank @PerfectProductions in #31 for the report!
