On my ppc musl system I get:

[Comment 3 Alfred Wingate 2025-05-31 00:58:01 UTC]

These systems have sys-libs/error-standalone installed?

tests/xargs/test-sigusr.c:34:10: fatal error: error.h: No such file or directory
   34 | #include <error.h>
      |          ^~~~~~~~~
compilation terminated.

So a case of having link the standalone error lib again specially for musl.

# emerge -p1v error-standalone

These are the packages that would be merged, in order:
