kbuild: rewrite check-local-export in sh/awk
Remove the bash build dependency for those who otherwise do not
have it installed. This also provides a significant speedup:
$ make defconfig
$ make yes2modconfig
...
$ find . -name "*.o" | grep -v vmlinux | wc
3169 3169 89615
$ export NM=nm
$ time sh -c 'find . -name "*.o" | grep -v vmlinux | xargs -n1
./scripts/check-local-export'
