This fixes:

  $ make installer
  (cd /tmp/qemu-nsis; \
           for i in qemu-system-*.exe; do \
             arch=${i%.exe}; \
             arch=${arch#qemu-system-}; \
             echo Section \"$arch\" Section_$arch; \
             echo SetOutPath \"\$INSTDIR\"; \
             echo File \"\${BINDIR}\\$i\"; \
             echo SectionEnd; \
           done \
          ) >/tmp/qemu-nsis/system-emulations.nsh
