vlang 0.3.5+ broken on PowerPC (macOS, FreeBSD, Linux); while 0.3.4 builds fine

[barracuda156]

Describe the bug

It is been a few months I compiler vlang last time on macOS ppc, and turns out it is broken now. The last version I built was 2023.15.
0.4.3 fails almost immediately on:

Reproduction Steps

sudo port -v install vlang on a PowerPC system.

Expected Behavior

vlang should build, as it did earlier.

So, 0.3.4 apparently is good (at least no closure failure), while 0.3.5 already broken.

Also broken on FreeBSD: https://www.mail-archive.com/[email protected]/msg2259602.html

@felipensp @spytheman @yuyi98 Could someone please look into this? While specific support for powerpc has not been there, it worked as of 0.3.4, but does not work since 0.3.5 anymore.

[felipensp]

We'll take care of it. Thanks for reporting.

@felipensp Great, thank you!
