In most cases "GLIBC_2.X" strings and `/lib/libc-2.x.so` files do not contain third (`patch`) field, which causes std.SemanticVersion.parse function to return error. To fix this, we reuse [now-public] std.zig.CrossTarget.parseVersion function, which accounts for this third field and makes it 0 in case it was not found. This new behaviour is similar to std.builtin.Version.parse, which was removed in6e84f46990Fixes regression from6e84f46990and https://github.com/ziglang/zig/pull/13998 . Related: https://github.com/ziglang/zig/issues/17626 . Results with `zig end`: Before: `"target": "x86_64-linux.6.5.7...6.5.7-gnu.2.19",` After: `"target": "x86_64-linux.6.5.7...6.5.7-gnu.2.36",` Also, while we are here, write explicit error sets and remove duplicate logic from std.zig.system.darwin.macos.parseSystemVersion .
