Hello,

gawk for ‘static-binaries-tarball’ is failing to build natively, at least for
x86_64-linux¹ and powerpc64le-linux. On both of them, the problem is the same:

This patch fixes it by passing “--allow-multiple-definition” to the linker.

Judging by the CI results, cross-builds seems to be working. I haven’t looked
into what’s different about them.

NB: I wasn’t sure how to write a changelog for ‘%static-inputs’ so I got a bit
creative.
