issue-21718: remove setting of PTHREAD_MUTEX_NORMAL
issue: https://github.com/openssl/openssl/issues/21718
build break reported:
crypto/threads_pthread.c:76:5: warning: implicit declaration of function 'pthread_mutexattr_settype'; did you mean 'pthread_mutexattr_destroy'? [-Wimplicit-function-declaration]
76 | pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_NORMAL);
| ^~~~~~~~~~~~~~~~~~~~~~~~~
| pthread_mutexattr_destroy
crypto/threads_pthread.c:76:38: error: 'PTHREAD_MUTEX_NORMAL' undeclared (first use in this function); did you mean 'PTHREAD_MUTEX_TIMED_NP'?
76 | pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_NORMAL);
| ^~~~~~~~~~~~~~~~~~~~
| PTHREAD_MUTEX_TIMED_NP
This occurs because PTHREAD_MUTEX_NORMAL is only defined in glibc if
__USE_UNIX98 or __USE_XOPEN2K8 is defined, which is derived from setting
__USE_POSIX_C_SOURCE or __XOPEN_SOURCE is selected in the glibc feature
set for a build. Since openssl selects no specific feature set from
glibc, the build break occurs
We could select a feature set of course, but that seems like a
significant discussion to have prior to doing so. Instead, the simpler
solution is to just not set the mutex type at all, given that
pthread_mutexattr_init sets the default mutex type, which should be akin
to normal anyway (i.e. no mutex error checking or allowed-recursive
behavior)
