configure.ac: allow user to specify READELF (#646) 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. Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
