Install of mono 5.18.0.268 on 64-bit Solaris 11/x86 (x86_64-pc-solaris2.11) with gcc 4.8.2 failed

[polonia]

I downloaded the last mono tar to Solaris 11
I install the required packages:

# pkg install autoconf
# pkg install automake
# pkg install libtool
# pkg install gcc

When I tried to configure mono 5.18.0.268 on 64-bit Solaris 11/x86 (x86_64-pc-solaris2.11) with gcc 4.8.2, it failed
like this:
$ ./autogen.sh

(...)
checking for PTHREAD_MUTEX_RECURSIVE... no
configure: error: Posix system lacks support for recursive mutexes

I changed the "D_XOPEN_SOURCE=500" to "D_XOPEN_SOURCE=600" in the configure.ac with no improvement

                                CPPFLAGS="$CPPFLAGS -D__EXTENSIONS__"
                                CPPFLAGS="$CPPFLAGS -D_XOPEN_SOURCE_EXTENDED=1"
                                LIBS="$LIBS -lxnet"
                                AC_MSG_RESULT(yes)
                        else
                                AC_MSG_RESULT(no)
                        fi

I am aware of the Bug 31999 - C99 and XPG5 don't match on Solaris 10+
https://bugzilla.xamarin.com/show_bug.cgi?id=31999

Acording to Oracle documentation, Solaris 11 supports thread mutex using Oracle Solaris Threads and POSIX pthreads API. Some functions are:

Oracle Solaris Threads	POSIX pthreads
mutex_lock()	pthread_mutex_lock()
mutex_unlock()	pthread_mutex_unlock()
mutex_trylock()	pthread_mutex_trylock()
mutex_init()	pthread_mutex_init()
mutex_destroy()	pthread_mutex_destroy()
-	pthread_mutexattr_init()
-	pthread_mutexattr_destroy()
type argument in mutex_init()	pthread_mutexattr_setpshared()
-	pthread_mutexattr_getpshared()
-	pthread_mutex_attr_settype()
-	pthread_mutex_attr_gettype()

I run

$ grep PTHREAD_MUTEX_RECURSIVE /usr/include/*
/usr/include/pthread.h:#define	PTHREAD_MUTEX_RECURSIVE		0x4
