Subject: [PATCH] drd/tests/pth_detached3: Make pthread_detach() call portable
 across platforms

pthread_t is opaque type therefore we can not apply simple arithmetic to
variables of pthread_t type this test needs to pass a invalid pthread_t
handle, typcasting to uintptr_t works too and is portable across glibc and
musl

Fixes
| pth_detached3.c:24:25: error: invalid use of undefined type 'struct __pthread'
|    24 |   pthread_detach(thread + 8);
|       |                         ^

[ bvanassche: reformatted patch description and fixed up line numbers ]
