   I believe the the root cause of the problem is this:
   
   1. When a Windows native tool is used (ie., CONFIG_CYGWIN_TOOL=y), then the compiler will return a Windows style path and not a POSIX compatible path
   2. the make 'dir' command expects a POSIX style path.
   
   So the solution might be to use cygpath to convert the windows path to a Windows path like:
   
       EXTRA_LIBS += -lgcc
       LIBGCC_PATH = ${shell $(CC) $(ARCHCPUFLAGS) --print-file-name=libgcc.a}
   
       ifeq ($(CONFIG_CYWGIN_WINTOOL),y)
         EXTRA_LIBPATHS += -L "${dir $(shell cygpath -u $(LIBGCC_PATH)}"
       else
         EXTRA_LIBPATHS += -L "${dir $(LIBGCC_PATH)}"
       endif
