Here is the test result on LoongArch, this is expected:

$ /opt/ltp/testcases/bin/getrlimit03
tst_test.c:2003: TINFO: LTP version: 20250530-81-ge1bb63ae5

It would be better if __NR_getrlimit_ulong can be printed as
__NR_ugetrlimit or __NR_getrlimit:

getrlimit03.c:80: TCONF: syscall(-1) __NR_getrlimit_ulong not supported

No strong opinion, let's see if other people have concern about it.

Thanks,
Tiezhu
