The process I (and others that I am familiar with) use is to define macros for common file extensions such as: EXEEXT, OBJEXT, and LIBEXT. You can conditionally define these in the makefile (or in a makefile that is included everywhere) to be the proper values for the target platform.

Example using gmake syntax:
ifeq ($(TARGET_OS), win32)
  EXEEXT=.exe
  OBJEXT=.obj
  LIBEXT=.lib
else
  ifeq ($(TARGET_OS), cygwin)
    EXEEXT=.exe
    OBJEXT=.o
    LIBEXT=.a
  else
    EXEEXT=
    OBJEXT=.o
    LIBEXT=.a
  endif
endif

Then when you define your targets:
foo$(EXEEXT) :
