These days as link-time optimisations spread accross compilers, they
tend to ship their own version of ld, ar, etc. Why not detect such
things if any. Users can select compilers by ./configure --with-gcc=
whatever, or select individual tool by e.g. ./configure NM=whatever.
The added AC_ARG_VAR macros enrich ./configure --help output.
