Bump the required automake version to 1.14

After the build system refactoring, we no longer call AM_PROG_CC_C_O
because it is obsolescent macro.  According to the automake manual the
`AC_PROG_CC` has been rewritten in automake 1.14 to not required the
call, thus we need to require at least automake version 1.14.
