Config file to reproduce

Hello,

using the latest buildroot commit 2989e3c87a1123350728904fd789ad513e76b073
I tried to build qt5base 11.1 with musl but I get errors about redefinitions
like statx_timestamp, statx and renameat2. Seems like there are collisions
between the linux headers and the musl headers ?

Steps to reproduce :

1) select musl as libc

2) select qt5base 11.1 in the target packages

3) make

Build output :
