math: add long double symbols when long double is same as double
To allow libmathlib.a to be a drop-in replacement for libc functions
on 32bit arm, we should provide long double symbols otherwise the
libc long double implementation may pull in double symbols that can
conflict with libmathlib.a in case of static linking.
Using wrappers instead of alias to avoid type declaration conflicts.
