Subject: [PATCH 1/6] gcc: use --enable-autolink-libatomic for platforms that
 often need atomics.

As explained in #35992, gcc often generates code that needs libatomic
on these platforms, so link to libatomic by default (as-needed).

Patches taken from Alpine.

+Subject: [PATCH] configure: fix detection of atomic builtins in libatomic
+ configure script
+
+Alpine's --enable-autolink-libatomic (which is enabled for riscv64 by
+default) causes the libatomic configure script to incorrectly detect
+which builtins are available on riscv64. This then causes incorrect code
+generation for libatomic since it assumes compiler builtins to be
+available which are not actually available on riscv64.
+
+This commit fixes this issue by disabling linking of libatomic configure
+test code entirely, thereby preventing linking against libatomic.
+
+See:
