Subject: [PATCH] CRuntime_Musl: Support v1.2.0 for 32 bits
As explained in the comment, `time_t` on Musl is now always 64 bits,
but used to be 32 bits on 32 bits systems.

+ * Musl versions before v1.2.0 (up to v1.1.24) had different

+ * This was changed to always be 64 bits in v1.2.0:
+ * https://musl.libc.org/time64.html
+ * This change was only for 32 bits system and
+ * didn't affect 64 bits systems
+ *
+ * To check previous definitions, `grep` for `time_t` in `arch/`,
+ * and the result should be (in v1.1.24):

+ * // arch/sh/bits/alltypes.h.in:21:TYPEDEF long time_t;
+ * ---
+ *
+ * In order to be compatible with old versions of Musl,
+ * one can recompile druntime with `CRuntime_Musl_Pre_Time64`.
