ar-compatible command for zig cc #7915
Description
When using zig cc when trying to compile xz, I get the following:
$ AR="zig build-lib" LD="zig build-lib" CC="zig cc" ./configure
<...>
$ make
<...>

error: unrecognized file extension of parameter 'cr'
Autotools are running zig build-lib with command cr, which it does not understand, thus failing.
It would be good to expose a compatible interface to ar, so zig cc is easier to integrate to existing toolchains.
Barring other issues, once this is resolved, xz can be built only with gnu make and zig.
