+Subject: [PATCH 6/6] Skip the search for dynamic libraries when static library
+ exists (#23593)
+
+This is a fix for a regression caused by #23336.
+
+Prior to #23336 all `-l` flags were expanded by emcc to full filenames,
+with `.a` files being searched for first. After #23336 we only expand
+the the paths of fake shared libraries which wasm-ld itself don't look
+for.
+
+Fixes: #23591
