New review comment by Phicem on void-packages repository https://github.com/void-linux/void-packages/pull/39984#discussion_r1002676787 Comment: I added these lines during my attempts to cross-compile to armv7l (from an x86_64 machine). Without them, I get a compiler error about a missing header: `fatal error: gnu/stubs-32.h: No such file or directory` Adding glibc-devel-32bit fixes this issue, but is not enough to make compilation work, because then there is another error: `/usr/include/math.h:462:21: error: '_Float128' is not supported on this target` Since cross-compilation does not work, I guess you're right and these lines are not needed.
