Correct: configure did not find it. (captured stdout of 
../src/bash-5.1.0/configure ...
checking for mkstemp... yes
checking for mkdtemp... no
checking for arc4random... no

Results in base directory:
config.h:/* Define if you have the mkdtemp function.  */
config.h:/* #undef HAVE_MKDTEMP */
config.log:configure:13967: checking for mkdtemp
config.log:ld: 0711-317 ERROR: Undefined symbol: .mkdtemp
config.log:| /* Define mkdtemp to an innocuous variant, in case 
<limits.h> declares mkdtemp.
config.log:| #define mkdtemp innocuous_mkdtemp
config.log:|     which can conflict with char mkdtemp (); below.
config.log:| #undef mkdtemp
config.log:| char mkdtemp ();
config.log:| #if defined __stub_mkdtemp || defined __stub___mkdtemp
config.log:| return mkdtemp ();
config.log:ac_cv_func_mkdtemp=no
root@x065:[/data/prj/gnu/bash/bash-5.1.0]

Attaching both configure.out and make.(std)out as well as config.log and 
config.status.

Hope this helps!
