pflash: Allow building under yocto.
The makefiles under external/* utilize the $(CROSS_COMPILE) variable
to determine the cross-compiler prefix. In a few places,
$(CROSS_COMPILE)gcc is called instead of $(CC). The issue with this is
that yocto build passes some compile flags as part of $(CC) instead of
$(CFLAGS), the most important of these is '--sysroot=...'. Without the
proper --sysroot flag, pflash compile fails to find critical libc
headers like stdio.h.
This change delegates setting of $(CC) and $(LD) to
external/common/rules.mk, which is widely used in the external tree, and
ensures that:
1) $(CC) is used instead of $(CROSS_COMPILE)gcc.
2) CC is only set when not passed from the environment.
