Bug #58699 cannot build with gcc dbg on solaris

cmake/os/SunOS.cmake:
  Remove TARGET_OS_SOLARIS
config.h.cmake:
  Remove TARGET_OS_SOLARIS
  Add PTHREAD_ONCE_INITIALIZER
configure.cmake:
  Add function for testing whether we need { PTHREAD_ONCE_INIT } rather than PTHREAD_ONCE_INIT
include/my_pthread.h:
  Use PTHREAD_ONCE_INITIALIZER if set by cmake.
include/mysql/psi/mysql_file.h:
  Include my_global.h first, to get correct platform definitions.
mysys/ptr_cmp.c:
  Hide the unused static functions in #ifdef's on solaris.
  Use __sun (defined by both gcc and SunPro cc) rather than TARGET_OS_SOLARIS
sql/my_decimal.cc:
  Include my_global.h first, to get correct platform definitions.
sql/mysqld.cc:
  Fix signed/unsigned comparison warning.
sql/sql_audit.h:
  Include my_global.h first, to get correct platform definitions.
sql/sql_plugin.h:
  Include my_global.h first, to get correct platform definitions.
sql/sql_show.cc:
  Fix: warning: cast from pointer to integer of different size
sql/sys_vars.h:
  Use reinterpret_cast rather than c-style cast.
storage/perfschema/pfs_instr.cc:
  Include my_global.h first, to get correct platform definitions.
