Before the change with x86_64-pc-linux-gnu cross-compiler
installed the configure was not able to find cross-readelf:
```
$ ./configure --host=x86_64-pc-linux-gnu
...
checking whether .eh_frame section should be read-only... .././configure: line 19540: readelf: command not found
yes
...
```
The change uses AC_CHECK_TOOL to automatically seatch for ${host}-readelf,
readelf. And as a bonus it also allows user to override readelf with
something like READELF=llvm-readelf.
