Revert "package/libopenssl: fix build on riscv32"
This reverts commit 2bb26c1a1d24cdbb946bc2a77680dbc8f9c0d537. There was some negative feedback from Arnd Bergmann on that patch: https://github.com/openssl/openssl/commit/5b5e2985f355c8e99c196d9ce5d02c15bebadfbc#commitcomment-44782859 The patch looks wrong to me: __NR_io_pgetevents_time64 must be used whenever time_t is 64-bit wide on a 32-bit architecture, while __NR_io_getevents/__NR_io_pgetevents must be used when time_t is the same width as 'long'. Checking whether __NR_io_getevents is defined is wrong for all architectures other than riscv And in light of the above, indeed the patch does not look so correct after all.

-Subject: [PATCH] Add support for io_pgetevents_time64 syscall
-
-32-bit architectures that are y2038 safe don't include syscalls that use
-32-bit time_t. Instead these architectures have suffixed syscalls that
-always use a 64-bit time_t. In the case of the io_getevents syscall the
-syscall has been replaced with the io_pgetevents_time64 syscall instead.
-
-This patch changes the io_getevents() function to use the correct
-syscall based on the avaliable syscalls and the time_t size. We will
-only use the new 64-bit time_t syscall if the architecture is using a
-64-bit time_t. This is to avoid having to deal with 32/64-bit
-conversions and relying on a 64-bit timespec struct on 32-bit time_t
-platforms. As of Linux 5.3 there are no 32-bit time_t architectures
-without __NR_io_getevents. In the future if a 32-bit time_t architecture
-wants to use the 64-bit syscalls we can handle the conversion.
-
-This fixes build failures on 32-bit RISC-V.
