RLIMIT_RTTIME is not provided by uclibc-ng or by musl prior to version
1.2.0 and
https://github.com/bminor/musl/commit/2507e7f5312e79620f6337935d0a6c9045ccba09
resulting in the following build failure since
https://git.qemu.org/?p=qemu.git;a=commit;h=244fd08323088db73590ff2317dfe86f810b51d7:
../linux-user/syscall.c: In function 'target_to_host_resource':
../linux-user/syscall.c:1057:16: error: 'RLIMIT_RTTIME' undeclared (first use in this function); did you mean 'RLIMIT_NOFILE'?
1057 | return RLIMIT_RTTIME;
| ^~~~~~~~~~~~~
| RLIMIT_NOFILE
Fixes:

Generally we prefer to fix this kind of problem with:
+#ifdef RLIMIT_RTTIME
case TARGET_RLIMIT_RTTIME:
return RLIMIT_RTTIME;
+#endif
Thanks,
