Comment 2 tt_1 2024-04-08 15:02:58 UTC 
I found this llvm pullrequest about fstat redefinition: https://github.com/llvm/llvm-project/pull/86625

but it doesn't fix the issue
Comment 3 Erik Hoppe 2024-04-28 07:50:44 UTC 
got the same issue on other 32bit arm targets, aarch64 seems to be fine.

Issue happens due to musl deprecating interfaces, that is supposed to be fixed upstream.
https://wiki.gentoo.org/wiki/Musl_porting_notes#error:_LFS64_interfaces_.28.2A64_undeclared_here.2C_ex._pread64.29

a workaround is to add -D_LARGEFILE64_SOURCE to your CFLAGS.
Comment 4 tt_1 2024-05-16 15:29:48 UTC 
Dear LLVM team, can we get -D_LARGEFILE64_SOURCE for a stable candidate of compiler-rt-sanitizers-18.1.x? It fixes the compile error on 32bit musl, thanks.

    profiles: only mask clang-runtime[sanitize] on 32-bit musl profiles
    
    The issue in the bug is only an issue on 32-bit musl platforms, not on
    64-bit. The original mask was overzealous, narrow the mask to arm, ppc,
    and x86.
