While I think the basic thrust here is correct, I dont believe the replacement
functions are neccessary;  I think it should be sufficient instead to just tweek
bits/std_cmath.h and shadow/bits/std_cmath.h.

s/BUILTIN_\([A-Z0-9]\+\)/s//BUILTIN_\1 \&\& _GLIBCPP_HAVE_\1/g

or perhaps

s/BUILTIN_\([A-Z0-9]\+\)/s//BUILTIN_\1 \&\& (_GLIBCPP_HAVE_\1 || _GLIBCPP_HAVE__\1)/g

this would have the advantage of inlining the call to the replacement (and
would handle all the other *f and *l that are found).
