commit 203ffc68468abaccfed7e8ee630d9aa143ce5dbf
Author: Paul Eggert <eggert@cs.ucla.edu>
Date:   Tue May 10 14:44:35 2022 -0700

    Port libm configure-time test to Solaris 11.4
    
    * configure.ac (LIB_MATH): Check all the math.h functions
    that Emacs uses, not just sqrt (Bug#55294).

introduced a test for log2.  But some versions of Android lack that
function, being one major operating system to not support all of the C99
math functions.

Does Emacs actually use log2 anywhere?
Would people be nice enough to make future uses conditional under
HAVE_LOG2?

Thanks.
