vmlinux.lds.h: catch more UBSAN symbols into .data
LKP triggered lots of LD orphan warnings [0]: mipsel-linux-ld: warning: orphan section `.data.$Lubsan_data299' from `init/do_mounts_rd.o' being placed in section `.data.$Lubsan_data299' mipsel-linux-ld: warning: orphan section `.data.$Lubsan_data183' from `init/do_mounts_rd.o' being placed in section `.data.$Lubsan_data183' mipsel-linux-ld: warning: orphan section `.data.$Lubsan_type3' from `init/do_mounts_rd.o' being placed in section `.data.$Lubsan_type3' mipsel-linux-ld: warning: orphan section `.data.$Lubsan_type2' from `init/do_mounts_rd.o' being placed in section `.data.$Lubsan_type2' mipsel-linux-ld: warning: orphan section `.data.$Lubsan_type0' from `init/do_mounts_rd.o' being placed in section `.data.$Lubsan_type0' [...] Seems like "unnamed data" isn't the only type of symbols that UBSAN instrumentation can emit. Catch these into .data with the wildcard as well.
