emulators/wine-devel: Unbreak on i386

Revert an upstream change to tools/winebuild/res32.c that exposed
resource contraints for clang on i386 (cf. the upstream reports
at https://github.com/llvm/llvm-project/issues/62339
and https://bugs.winehq.org/show_bug.cgi?id=54889 ).

Apply this patch only on i386 to minimize divergence and risk on
64-bit x86.

+The upstream change

+  commit 0b3f90ab1485d5bd32bd72d41c7fd8213b3b95b9

+
+    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).
