Convert libs to a fixed-point This does break the API of being able to import any lib file and get its libs, however I'm not sure people did this. I made this while exploring being able to swap out docFn with a stub in #2305, to avoid functor performance problems. I don't know if that is going to move forward (or if it is a problem or not,) but after doing all this work figured I'd put it up anyway :) Two notable advantages to this approach: 1. when a lib inherits another lib's functions, it doesn't automatically get put in to the scope of lib 2. when a lib implements a new obscure functions, it doesn't automatically get put in to the scope of lib Using the test script (later in this commit) I got the following diff on the API: + diff master fixed-lib 11764a11765,11766 > .types.defaultFunctor > .types.defaultTypeMerge 11774a11777,11778 > .types.isOptionType > .types.isType 11781a11786 > .types.mkOptionType 11788a11794 > .types.setType 11795a11802 > .types.types This means that this commit _adds_ to the API, however I can't find a way to fix these last remaining discrepancies. At least none are _removed_.

lib.systems: add powerpc64-linux PPC64 supports two ABIs: ELF v1 and v2. ELFv1 is historically what GCC and most packages expect, but this is changing because musl outright does not work with ELFv1. So any distro which uses musl must use ELFv2. Many other platforms are moving to ELFv2 too, such as FreeBSD (as of v13) and Gentoo (as of late 2020). Since we use musl extensively, let's default to ELFv2. Nix gives us the power to specify this declaratively for the entire system, so ELFv1 is not dropped entirely. It can be specified explicitly in the target config, e.g. "powerpc64-unknown-linux-elfv1". Otherwise the default is "powerpc64-unknown-linux-elfv2". For musl, "powerpc64-unknown-linux-musl" must use elfv2 internally to function.
