C and POSIX allow any of their standard functions to be provided as
macros too, but the function definition must always be provided. The
reason I put the macro in musl is simply that it's easy to do and
gives better code (trivial inline comparison rather than spilling all
registers and making a function call) and it's not something where the
implementation could change or need to change.
