    lto: Always quote path to touch
    
    When generating the makefile, make sure that the paths are quoted so
    that a native Windows path works within Cygwin.
    
    Without this patch, this error is reported by the DejaGNU test suite:
    
    make: [T:\ccMf0kI3.mk:3: T:\ccGEvdDp.ltrans0.ltrans.o] Error 1 (ignored)
    
    The generated makefile fragment without the patch:
    
    T:\ccGEvdDp.ltrans0.ltrans.o:
      @T:\build\bin\arm-none-eabi-g++.exe '-xlto' ... '-o' 'T:\ccGEvdDp.ltrans0.ltrans.o' 'T:\ccGEvdDp.ltrans0.o'
      @-touch -r T:\ccGEvdDp.ltrans0.o T:\ccGEvdDp.ltrans0.o.tem > /dev/null 2>&1 && mv T:\ccGEvdDp.ltrans0.o.tem T:\ccGEvdDp.ltrans0.o
    .PHONY: all
    all: \
      T:\ccGEvdDp.ltrans0.ltrans.o
    
    With the patch, the touch line would be replace with:
    
      @-touch -r "T:\ccGEvdDp.ltrans0.o" "T:\ccGEvdDp.ltrans0.o.tem" > /dev/null 2>&1 && mv "T:\ccGEvdDp.ltrans0.o.tem" "T:\ccGEvdDp.ltrans0.o"
    
    gcc/ChangeLog:
    
            * lto-wrapper.cc: Quote paths in makefile.
