make[1]: *** [arch/um/kernel/irq_user.o] Error 1
make: *** [arch/um/kernel] Error 2

This is because uclibc's string.h has this snippet:

#ifdef	__USE_BSD
/* Two OpenBSD extension functions. */
extern size_t strlcat(char *__restrict dst, const char *__restrict src,
                      size_t n) __THROW;
extern size_t strlcpy(char *__restrict dst, const char *__restrict src,
                      size_t n) __THROW;
#endif
