configure.ac: use compiler-provided toolchains
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.
