If target is bpf, there is no __loongarch__ definition, __BITS_PER_LONG
defaults to 32, __NR_nanosleep is not defined:
#if defined(__ARCH_WANT_TIME32_SYSCALLS) || __BITS_PER_LONG != 32
#define __NR_nanosleep 101
__SC_3264(__NR_nanosleep, sys_nanosleep_time32, sys_nanosleep)
#endif
Check __TARGET_ARCH_loongarch to include arch specified bitsperlong.h,
then __BITS_PER_LONG is 64, __NR_nanosleep can also be defined to fix
the following build errors:
clang -g -Werror -D__TARGET_ARCH_loongarch ... -target bpf -c progs/test_vmlinux.c ...
