This is off because __SIZEOF_PTHREAD_ATTR_T is defined by uClibc-ng,
for example for AArch64:
libpthread/nptl/sysdeps/unix/sysv/linux/aarch64/bits/pthreadtypes.h:#define __SIZEOF_PTHREAD_ATTR_T 64
libpthread/nptl/sysdeps/unix/sysv/linux/aarch64/bits/pthreadtypes.h: char __size[__SIZEOF_PTHREAD_ATTR_T];
Perhaps there's an include missing in gcc ?
However, musl does not define __SIZEOF_PTHREAD_ATTR_T.

Fair enough, but it should be explained with a short comment above the
dependency.
Thanks!
