	Use objconv when compiling with Apple's CC

	* conf/i386-pc.rmk (efiemu32.o): use OBJCONV if defined
	(efiemu64.o): likewise
	(efiemu64_c.o): omit -mcmodel=large and add -DAPPLE_CC=1
	when compiling with Apple's CC
	(efiemu64_s.o): likewise
	* configure.ac: check for objconv when compiling with Apple's CC
	* genmk.rb: use objconv for modules when compiled with Apple's CC
