Support GLIBC version targeting, example:
`cmake -B build -G Ninja --toolchain cmake/x86_64-linux-gnu.2.17.cmake`
(You would need to create this file)
Because `NAME_WL` was used all extension info was lost, with `NAME_WLE` along with the regex change on the ABI match group we're able to recover and use the full ABI target string from the filename.
