ldlinux: Don't delete ldlinux.c32 with 'make clean'

The documented command sequence for distributions wishing to package a
Syslinux release is,

	 make clean
	 make installer

Unfortunately, becaues ldlinux.c32 is deleted by 'make clean' the
installer target fails like so,

make[1]: *** No rule to make target `../com32/elflink/ldlinux/ldlinux.c32', needed by `ldlinuxc32_bin.c'.  Stop.
make: *** [installer] Error 2

Follow the example set by core/Makefile for ldlinux.sys, etc and add
any build files that are required by the installers to
$(BTARGET). $(BTARGET) only gets deleted when running 'make spotless'.
