Chromium failing on aarch64 in rawhide

[Tom Callaway <spotrh@xxxxxxxxx>]

This one is odd. Chromium is failing on aarch64 in rawhide, on a bit of ffmpeg code that has not changed in _years_.

[clear_key_cdm:13/13] g++ -shared -Wl,--fatal-warnings -fPIC -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now -Wl,-z,defs -Wl,--as-needed -Wl,-O2 -Wl,--gc-sections -rdynamic -o "./libclearkeycdm.so" -Wl,-soname="libclearkeycdm.so" @"./libclearkeycdm.so.rsp"
FAILED: libclearkeycdm.so
g++ -shared -Wl,--fatal-warnings -fPIC -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now -Wl,-z,defs -Wl,--as-needed -Wl,-O2 -Wl,--gc-sections -rdynamic -o "./libclearkeycdm.so" -Wl,-soname="libclearkeycdm.so" @"./libclearkeycdm.so.rsp"
obj/third_party/ffmpeg/ffmpeg_internal/videodsp.o: in function `ff_prefetch_aarch64':
(.text+0x10): relocation truncated to fit: R_AARCH64_CONDBR19 against symbol `ff_prefetch_aarch64' defined in .text section in obj/third_party/ffmpeg/ffmpeg_internal/videodsp.o

The function it references is defined in libavcodec/aarch64/videodsp.S:

function ff_prefetch_aarch64, export=1
        subs            w2,  w2,  #2
        prfm            pldl1strm, [x0]
        prfm            pldl1strm, [x0,  x1]
        add             x0,  x0,  x1,  lsl #1
        b.gt            X(ff_prefetch_aarch64)
        ret
endfunc

Did something change in rawhide that might be breaking this?

Thanks in advance,

Tom
