+Subject: [PATCH 4/4] qmake: Fix building with lld with mingw makefiles
+
+lld for coff/mingw doesn't support linker scripts, which qmake used
+for passing larger numbers of input file names to the linker.
+
+Instead of using a fullblown linker script for this, just use a plain
+response file, which both lld and binutils ld support.
