1. Fix linking to 64-bit time_t versions of functions on musl …

   musl switched to 64-bit time_t across all architectures in version
   1.2.0:
   
   https://musl.libc.org/time64.html
   
   This change was done in a way which attempted to preserve ABI
   compatibility. To achieve this, the 32-bit versions of functions were
   left at their original names in the compiled library, and new 64-bit
   versions of functions were introduced. The header files then
   redirected calls to the standard function names to use the new 64-bit
   versions using the __asm__("name") construct, which is similar to D's
   pragma(mangle, "name").
   
   This change is a fix-up for commit
   ca0b670, which tried addressing this
   change in musl by changing time_t to 64-bit when targeting new musl
   versions (the default). However, that change was incomplete, as it did
   not implement the function redirection part of the change, which is
   required to actually call the implementations using 64-bit time_t. As
   a result, it caused programs to link but return incorrect results at
   runtime on 32-bit architectures when targeting new musl versions.
   
   Fix this by adjusting the mangled name of the D declarations of
   affected functions when targeting musl on 32-bit platforms.  Affected
   functions in musl can be found by grepping for _REDIR_TIME64 and uses
   of the __REDIR macro.
   
   Fixes issue 23608.
