The upstream change

  commit 0b3f90ab1485d5bd32bd72d41c7fd8213b3b95b9
  Author: Rémi Bernon <rbernon@codeweavers.com>
  Date:   Sat Feb 11 11:05:22 2023 +0100

    winebuild: Use .incbin instead of printf for resource data.

apparently causes some (not completely reproducible) build
issues on i386 due to resource exhaustion by the compiler,
cf.  https://bugs.winehq.org/show_bug.cgi?id=54889 .

https://github.com/llvm/llvm-project/issues/62339 tracks this on
the LLVM side, alas has not really seen progress since April 2003.
So for now this reverts the upstream commit (alas on i386 only as
to minimize divergence and risk on 64-bit x86).
