Andrew Kelley 4616af0ca4 introduce operating system version ranges as part of the target ... * re-introduce `std.build.Target` which is distinct from `std.Target`. `std.build.Target` wraps `std.Target` so that it can be annotated as "the native target" or an explicitly specified target. * `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a struct which has the tag as well as version range information. * `std.elf` gains some more ELF header constants. * `std.Target.parse` gains the ability to parse operating system version ranges as well as glibc version. * Added `std.Target.isGnuLibC()`. * self-hosted dynamic linker detection and glibc version detection. This also adds the improved logic using `/usr/bin/env` rather than invoking the system C compiler to find the dynamic linker when zig is statically linked. Related: #2084 Note: this `/usr/bin/env` code is work-in-progress. * `-target-glibc` CLI option is removed in favor of the new `-target` syntax. Example: `-target x86_64-linux-gnu.2.27` closes #1907		2020-02-28 14:51:53 -05:00
