Use $(obj)/ instead of $(src)/ prefix when building C++ modules for
host, as explained in commit b1992c3772e6 ("kbuild: use $(src) instead
of $(srctree)/$(src) for source directory"). This fixes build failures
of 'xconfig':
$ make O=build/ xconfig
make[1]: Entering directory '/data/linux/kbuild-review/build'
GEN Makefile
make[3]: *** No rule to make target '../scripts/kconfig/qconf-moc.cc', needed by 'scripts/kconfig/qconf-moc.o'. Stop.
Fixes: b1992c3772e6 ("kbuild: use $(src) instead of $(srctree)/$(src) for source directory")
