Stale cache somehow? I explicitly unmarked it as broken. I'm running nixpkgs-review on x86_64-linux, but it's taking its time. |

Looks like MAME works on macOS, so we need someone who can run it to correct the dependencies. Our current MAME derivation might be of some help. |

Builds currently fail with `ar` trying to operate on what are clearly two paths concatenated together. It stems from a backward-incompatible change in Make: > Previously appending using '+=' to an empty variable would result in > a value starting with a space. Now the initial space is only added > if the variable already contains some value. Similarly, appending an > empty string does not add a trailing space. This issue was first reported on the MAME repository proper (mamedev/mame#6248), and affects libretro's 2016 snapshot as well. A fix that is reported to work with previous versions of Make was upstreamed to: - GENie, the build system: bkaradzic/GENie#493 - MAME: mamedev/mame#6262 - libretro: libretro/mame2016-libretro#47 The fetched patch comes from the last of these. (cherry picked from commit 8880179)

It was found out in the course of NixOS#102078 that the libretro.mame* packages did not build on macOS, both because of an unconditional dependency on alsa-lib (which is exclusive to Linux) and references to GCC scattered across makefiles. This commit makes alsa-lib a dependency only on Linux, and tries to force usage of the generic `cc`/`c++` commands. Ideally we'd refer to the `$CC` and `$CXX` environment variables, but that seems to introduce recursive expansion problems for make. Thanks to @SuperSandro2000 for suggestions and actual testing.

Thanks for the backport as well 👍 |
