btw last time i looked at clang, mostly to build musl, the
main issues were incompatible inline asm handling on some
targets breaking inline syscalls and lack of fenv support
breaking libm.

and in glibc i'd expect the nested functions in the dynamic
linker to be challenging to fix: that will affect generic
and target code too.
