to be installed when linking libc. When zig links against libc, it requires a dynamic linker path. Usually this can be determined based on the architecture and operating system components of the target. However on some systems this is not correct; because of this zig checks its own dynamic linker. When zig is statically linked, this information is not available, and so it resorts to using cc -print-filename=foo to find the dynamic linker path. Before this commit, Zig incorrectly exited with an error if there was no c compiler installed. Now, Zig falls back to the dynamic linker determined based on the arch and os when no C compiler can be found.
