[Buildroot] [PATCH] package/liburing: Configure liburing with --use-libc

[Charlie Jenkins]

liburing requires libc when building for any architecture that doesn't
have built-in syscall support (that is currently any architecture other
than x86 and aarch64). Configure liburing with --use-libc to allow these
other architectures to compile.

Sorry for the super long delay in getting back to you. However, it
seems like the issue doesn't exist anymore. First the nolibc mode
exists for RISC-V 64-bit now, and enabling libc seems to be done
automatically on other architectures. I can happily build liburing on
say PowerPC 64 for example. Also our autobuilders are not reporting
any issues.

Building on RISC-V 64-bit, which has nolibc support shows:

nolibc                             yes

during the configure step.

Building for PowerPC 64 build:

nolibc                             no

So I believe your patch is no longer needed.

Best regards,

Thomas
