libstdc++: testsuite: Guard use of C99 std::log2

This prevents the test from failing if the only thing not supported is
the text printed to the log about the size of the floating-point type.

libstdc++-v3/ChangeLog:

* testsuite/20_util/from_chars/4.cc: Only use log2 if C99 math
functions are available.

(cherry picked from commit 30aea28bd30027e0a6be8e3077828256779954b3)
