[Buildroot] [PATCH v2 1/1] package/crucible: needs NPTL

[Bernd Kuhls]

gcc_stack_unix.c: In function 'x_cgo_getstackbound':
gcc_stack_unix.c:28:9: error: implicit declaration of function 'pthread_getattr_np';
 did you mean 'pthread_attr_init'? [-Wimplicit-function-declaration]
   28 |         pthread_getattr_np(pthread_self(), &attr);  // GNU extension

Fixes:
https://autobuild.buildroot.net/results/e07/e07198d7864331027d21cd2109054d86e7ac1c3d/

The build error also occured in Oct 2024 so a backport to buildroot
LTS branches should be considered:

Thanks, applied to master, after fixing one small thing.
