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.
