meson.bbclass: fix to build for more projects

We should use the value of CC for the c compiler setting in cross
compilation configuration file for meson. For example, if we only
use ${HOST_PREFIX}gcc instead of ${CC}, we would meet the following
do_compile failure for systemd.

  cc1: fatal error: linux/capability.h: No such file or directory

Do the same change for LD, AR, NM, STRIP and READELF.
